Here is a bad picture of where to put the other end of the extension. You will want to use a non-insulated blade connector to push in next to the wire terminal. The wire that the extension needs to be connected to is the larger green/white wire which attaches to the underside of the Tail relay.

Hope this helps.

I want to have the fog lights on with the parking lights and headlights (not the ignition on option).

I read this post and the one from Maniac to accomplish this.....this one says connect to a green/white wire of the Tail relay, and Maniac's post says connect to a Black/Red wire of the tail relay. Whats the difference????

BTW I know this is a revisit of an old post....I assume the wires are the same in my 2005.

I just did the mod tonight following Maniac's instructions, except I used a tap-in connector. Works perfectly!

These do the same thing in theory, one is connected to the tail relay, the other (Maniacs) to the tail fuse. I tried the green/white first, and while it worked, I didn't like the fact that the connector was just wedged in there. I didn't have a tap-in connector for the larger green/white wire, so I pulled it out and connected it to the red/black.

You guys that figured out these different variations of this mod have heard it all before, but you rock! :rock: Thanks a lot!

Thanks for the info. It was an even simpler mod than I thought it would be, especially with the excellent pictures.

As others have noted, the foglights do not have an impressive output by themselves. I think that they are most useful as daytime running lights. I would like to make them function more as fog lights (greater light output). Has anyone tried replacing the H11 bulbs with H9s? This site, Daniel Stern Lighting Consultancy and Supply (http://www.danielsternlighting.com/products/products.html), suggests that it is possible, and that there would be a significant gain in light output if the foglight fixture itself can handle the increased light from the H9 without causing excessive glare.

Looks like it would work. The H9 is inexpensive and I may have to give this mod a try.The difference in light output between these two designs is enormous (1350 lumens from the H11, 2100 from the H9), so putting an H9 in place of an H11 will obviously cause the lamp to produce a lot more light. Some lamps are designed such that the optics will handle the extra light well, without creating excessive glare for other road users.

I have been thinking of h9's as well. I was looking at the fog lights today and was wondering....how the heck do you get to the bulbs? :spank:

It's pretty easy - you can do it from below, unscrew the plastic undertray, and you can reach in to remove the bulb, turning the socket counterclockwise a 1/4 turn.

I just replaced my bulbs today, I just removed the 3 screw/bolts from the diffuser (the plastic undertray tamas is referring to). I them opened the diffuser enough to get my hand in there and removed/replaced the bulbs.

I did this mod yesterday (finally) with some bulbs I bought from Autolumination.com. I just want to thank the pioneers who figured this out. Magnesium and Omicron- you guys rock! I decided to do the Omicron variation, because I wanted the functionality of turning them on whenever the key was in the on position. Now I'm rockin it with white/blue front marker led's and bright yellow fogs! (By the way, if any of you guys need to get lights, check out autolumination. I got all four bulbs I needed for under $20, including shipping. I can't speak to the longevity of the bulbs... but they are very nice looking.)

I repaced the original forlight H11s with H9s. They are much brighter (they are the same bulbs that are used for the highbeams).

The H9s fit into the fog light housings. However, there is one hitch to the installation, the H9 and H11 bulbs have different contact alignment tab configurations and the foglight wiring connector will not fit onto the H9 bulb. I will not dwell on how long it took me to realize this :Eyecrazy: . The most elegant mod would be to replace the H11 wiring connectors with ones that fit H9s. But I was impatient, so I just modified the bulbs.

The H11 bulbs have a single plactic alignment tab between the contacts. The H9 bulbs have two of these tabs. They are between the contacts also but one on each side. I just removed the alignment tab from the H9 bulb that is not on the H11 bulb. The wiring connector then went right on.

The easest way to remove the tab would be to use a dremel tool, but I did not have one. I used a drill bit and "routed" it out. I secured the bulb base in a vise while I did this. I bent the contacts doing this, but they were easy to straighten.

I am comfortable driving up to 40-45 mph on a dark country road with only the foglights on (had to try them). Maybe they will work as real fogs now - they have to be better than they were.

What is the wattage of a H9 bulb? I replaced my stock 55w H11s with 80w bulbs. The bulbs started to bulge out from the heat. I put the stock bulbs back in. Inside the fog housing their is another housing that seems to block direct light from the bulb. This will contain heat, I wonder if its possible to remove this internal housing.

H9 - 65 W

H11 - 55 W

The following is from the Daniel Stern web site:

"the H9 has different base keys than its H11 low-beam counterpart. Somebody goofed on the spec, though, for the difference between H11 and H9 base keys are insufficient; it's too easy to install an H9 bulb where an H11 belongs. The difference in light output between these two designs is enormous (1350 lumens from the H11, 2100 from the H9), so putting an H9 in place of an H11 will obviously cause the lamp to produce a lot more light. Some lamps are designed such that the optics will handle the extra light well, without creating excessive glare for other road users."

Was it the outer lens that deformed with the 80W?

I don't think it wsa the outer lens the deformed the 80w bulb, but the internal housing. Its a gray housing that the bulb slips into, it looks like it can be removed. I also read a thread here that someone's outer lens cracked due to using a higher wattage bulb 100w. Keep us updated on the H9s let us know if you have any problems.

feel like I'm resurrecting this thread from the grave, but I HAD to send a shout out...

Sounds like a nice mod...kudos to the founders :ylsuper:

I've did this same mod to my 97 Cobra and Probe, and I know first hand the hours and time it takes to locate the wires and know that understanding which wires go to which relays can be aggravating.

From the pics, the fuse box location is TOO convient too! Not to onset a pity-party, but in BOTH my Cobra and Probe, you had to pull switches out of the (Probe) center console, and (Cobra) center column. You think you have short wiring to work with here? HA...I can tell you first hand that we should be so lucky to have THIS much wire play as the 8 does. Mazda got one part right for sure... :worship:

Much thanx goes out to the pioneers of the mod, including Magnesium, Omicron and Bobclevenger. You guys saved hours of time for anyone whos up on this mod

NOTE FOR CANADIAN CARS.....
To bypass the DRL module (behind the glovebox) you need to connect the 'fog in'(light green&black) and 'fog out'(yellow&red) at the big DRL connector. They are side by side at the lower left of the connector. Also, the 'brown' wire on US cars is 'brown&white' striped for DRL models, but it IS the same wire as in the Omicron instructions.

I can't find this module... behind the globe box? Which one?

That part is there to make sure that you get a well-defined output pattern. If light were allowed to come directly from the front of the bulb, it would produce a lot of "spill" light in all directions, which is not something you want in a fog light -- you want most of the light being formed by the reflector, into a desirable pattern. Most bulbs will have the top of the bulb masked already, but that little piece of metal is cheap insurance.

Much love to Omnicron, Magnesium, and Bobclevanger! The directions for the fog light mod we perfect, only took 10 minutes and now I can run the fogs when and how I want.

Very cool.

Be sure to switch the fog switch off if you take the car in for service. I had the gas tank recall done last week and forgot to switch off my "always on when switch is on" fogs off. When I picked up the car I noticed that someone had turned off the fog switch - I guess they wondered why they were always on when the key was on. I am lucky they were not concerned enough to try to "fix" the problem.

I will remember to switch them off next time :D

Has anyone figured out the variation of this mod that will keep the fog lights on ALL the time - bypassing the foglight switch all together?

This would be an excellent solution for those who want to turn the foglights into "true" DRLs - for insurance discounts or to make US spec cars compliant in Canada.

Anyone know the wiring modification to bypass the switch all together? It would be most appreciated!

To turn the lights on whenever the ignition is on is fairly simple.

The fog relay gets it's power from the headlight relay, so no headlights = no fogs.
The switch just grounds the relay coil.

So you would need to disconnect the W/B wire on the fog relay, and get switched power to the relay from the W/R terminal of the "acc" relay (close to the fog relay).

Then you would disconnect the LG/B wire on the relay, and wire it to a ground, this bypasses the switch.

10-20-2006, 12:17 PM
Right on StealthTL! Thanks !

It worked great. I rewired my fog lights as outlined by Omicron.. Then I grounded the light-green/black wire from the fog light relay to a ground (I used the bolt in front of the fuse box - I needed to add extra wire on to the LG/B wire to extend it that far) and it works!

My fogs are now always on whenever the ignition key is in the 'On' position, regardless of where the fog light switch is. (And that makes the car compliant with Canadian DRL laws - excellent!). :mdrmed:

There are 274 posts in this thread, talking about everything from wiring the fog lights as daytime running lights, to changing bulbs, to wiring side marker lights as "repeaters", etc, etc, etc.

All I want is to have my fog lights work independently of the headlights, so I can actually use them as fog lights in an actual fog.

I don't have time to read each of the 274 posts—can anyone refer me to exactly what I need to do?

Thanks so much!

So you want US to read the 275 posts and tell you which one to follow? Sorry, *I* don't have that kind of time :Eyecrazy:

I have mine wired where they are connected to the accessory power as is described here someplace. The foglight switch controls them so I can have fogs only, fogs w/parking lights, fogs w/low beams, fogs w/high beams (makes no sense) if I want. Just read along until you find the proper post - you connect the same wire from the fog light relay it just depends on where you connect the other end - I sure don't remember the details, but it is all here with pictures.

Be sure to switch the fog light switch OFF if/when you take your 8 into the dealer for service. Having the log lights on w/o the low beams could make them think something was WRONG with your car and then open the fuse/relay box and "find" your mod.

Wouldn't it be simpler and more reversable to remove the relay and jumper the power pins for the fogs?

18bsTiRX8
01-29-2007, 02:15 PM
No, at least I don't think so.

The 'Brown' wire is the trigger for the Fog Light Relay and goes "hot" when the headlights are receiving power. If you jumper the Fog Light Relay switching terminal to the Tail Light relay or Accessory relay, you will give power to the Fog Light Relay and allow them to turn on early, BUT you will also be putting power into the 'Brown' wire to which is connected to the headlight circuit.

Without looking at the wiring diagrams, I am not sure what adverse affect (if any) this may create. But I imagine you will still have to cut the 'Brown' wire.

It is definately another way of solving the same problem, but if you still must cut the 'Brown' wire, I think the soldering to the Tail Light relay trigger wire ('Black/Red') would make a more solid connection with less risk of fire or blown fuses.

Just my 2cents....

PS I organized the DIY from "Maniac" for using the 'Brown' and 'Black/Red' wires in order to have an OEM-like function, with fogs coming on with parking lights. I put the pictures and instructions into a more printer friendly format in a Word doc. Unfortunately, it appears to be too large to attach on here. Anybody willing to host it and post up a link? Leave me a PM with an email addy so I can send the file.

Credit goes to Maniac, Post #62 for the best and most professional method, in my opinion.

01-30-2007, 11:19 AM
green wire? I must have missed that set of instructions!

I know of 2 methods (but I didn't spend hours sifting through this thread):
1 - Brown wire into Black/Red wire --> fog lights go on with parking (running) lights

2 - Brown wire into small White/Red wire --> fog lights can go on anytime you turn on the fog light switch independent of headlights AND parking lights.

I have no clue about a green wire????

Hmm, I think we might be on different wavelengths here. That or I'm completely talking out of my ass.

The relay (and it's socket) should have four terminals that we are concerned with. Two for signal/switching (headlight) and two for providing power to the switched circuit (fogs). There may be more, depending on whether or not it's more than just an SPST relay. My idea is to just short the switched terminals on the relay (or it's socket) so that it doesn't matter if the relay is open, closed or not even present, power will still flow to the fog lights.

Unless I'm way off here and the power for the fog lights comes from the same circuit that triggers the relay (which I don't see as very likely as the fogs have their own switch).

I'm probably being a little noobish here as my electrical knowledge is somewhere just below beginner.

dwynne
02-04-2007, 05:36 PM
If you bypass the relay, the fogs will always be on as long as the log switch inside the car is on. So if you forget to turn that switch off, you will drain your battery.

The various ideas here tie the control line of the fog relay into something like a parking/running light or to the switched +12v. Then the fogs come on when the switch on when the parking or headlights or on or when you turn the key on. In both cases, turning off the key and the lights will result in the fogs goinf off automatically even if the switch is left on.

I wired mine to the switched accessory source and use them as DRLs - the come on and off with the key (unless I turn off the fog switch). I did a similar mod on my new "snow day" car, a Scion xB and again use them as DRLs.

Yea, I think we might be a different wavelengths here :)

I think the mod you are suggesting is to create a DRL situation; in other words, fogs come on with ignition.

My understanding of the relay switching circuit is that yes, there is generally 4 terminals. Two of the terminals can be thought of as the high current input/output...essentially a break in the main power wire. This "break" in the main power cable becomes connected by the internal switch which is triggered by power to the "switching" circuit. This is made up of the other two terminals, one of which provides + power to the relay switch itself, and the other is - ground.

Once again, I am not sure I followed you correctly, but when you said you are not concerned with whether the relay is open/closed, you are suggesting jumping the input/output terminals together.

Generally speaking, high current lighting applications require the use of a relay to isolate the switching system from the high current wire, mainly to protect the switch itself. The high current wire (on the input/output terminals of the relay) is usually connected directly to a main power distribution point on the battery.

If you short the two main wires together, you are by-passing the switch and I believe the result will be fogs that are on until your batter dies regardless of any relay (or interior headlight switch).

I still believe this entire long thread can be summed up with two high quality/reliable DIYs:

1) For a DRL effect, where the fogs come on with ignition (unless you turn off the fog light switch on the stalk): cut the "Brown" wire and connect the fuseblock side of the cut wire to the small white/red-stripe wire (ACC)

2) For the same OEM-like function where the fog light switch on the stock can be left on, but the lights only come on with a lighting circuit (modded to the parking light circuit instead of the OEM method of the headlight circuit): Cut "Brown" wire and connect fuseblock side of cut wire to the black/red-stripe wire on the parking light circuit.

dwynne
02-07-2007, 12:45 PM
I will add to your summary:

If you do the mod, but sure to turn off the fogs (at the stalk) when you take the car into the dealer for service. If they notice any difference from normal behavior they may investigate or try to "fix" it. If you turn them off at the stalk the odds are very slim they will even look at them at all.

i read through all the post...well skimmed. do i use the black/red or green/white? i want the fogs to go on when i use the DRL or headlights, not anytime i want.

the fogs also go off when i turn off the DRLs right?

Hi Jeff,

Thanks for the step-by-step + detailed photos. It's much more easy to follow for a newbie like myself. If you don't mind, I have quick follow-up questions as well..

What do u do to protect the other side of the cut brown wire? (ie the side no longer connected to the relay.) do u just use electrical tape to cover the tip or is it safe to just leave it dangling?

Also, is it true that your flavor of this mod is actually "safer" than Omicron's ACC one? It sounds safer to me, because it doesn't mess w/ the ACC wire (ignition) at all, which could potentially mean your car won't start if you mis-wire or do something incorrectly.

Thanks in advance for clarifying these points for me.

Attach the BROWN wire to the stripped section of the BLACK and RED wire, solder the connection and cover the junction with the shrink tubing. Shrink the two sections of tubing with the heat from the solder gun:[/b][/i][/COLOR] [/SIZE]

Argh - why can't I do something so simple.......

Brown Wire goes from blackbox to thin white w/ red strip wire two blackboxes down.

Right??

At one point the lights were all flickering crazy. Then I rewired and got lights working normally (except fogs would never come on). I've reversed all changes out, but now the car won't start.

Well, this wasn't exactly a quick mod for me. My first mistake was trying to wiretap using the the brown wire leading away from the box. My second mistake was using cheap connectors/wiretap. My third mistake was not recoginizing a blown fuse.

Those 3 led to all sorts of confusion. A very easy Mod, if you take your time. I tried to rush it and screwed stuff up. =)

But - the car is okay now, AND i can turn on my fogs whenever I want now (did Omicron method)

Does anybody know a way to wire it so the fog lights come on with the ignition whether or not the switch is turned on, but then turn off when the high beams are activated. This it the requirement to pass a provincial inspection for DRL's on a Canadian automobile.

I'll be moving on to modify an H9 bulb to fit the H11 foglight socket so I can get more light...

Don't know if this had been posted before but I just did this mod, had no soldering experience or equipment. Used a 22-18 gauge Quick Splice that you can pick up at any auto store. Worked great, and is secure (better than electrical tape).

Maniac, thanks for the instructions, couldn't have penetrated that forest of wires w/out.

question jus to clear things up for me - you cut the brown wire first and you have to connect that wire with what other wire.. i think the small black and red wire? am i right? this is to use the fogs when the parking lights are on and also.. if i want.. when the headlights are on

This is still one of the coolest mods. It even helps me protect the life of my HID lamps. I park in a parking garage and I like to turn on some lights for visibility. Turning on HID is very hard on them -- you only get so many starts so it's bad to waste them on 5 minute runs. With the fog light rewire I can use the fogs instead. Brilliant!

I just did my mod the way that Omicron suggested several pages ago in this thread. Only thing i did different was this:

My brown wire was long enough to just reach over to the ACC realy and connect dirrectly in without splicing or using the addtional red wire that was previously suggested. Works great thanks!

Brilliant mod! Just did it in 15 minutes. half of which was finding a pair of pliers to clip the vampire tap onto the wires completely. Used maniacs method so they come on with the parking lights. folded over the remaining brown wire and heatshrinked it to itself to prevent a short.

I forgot if this has been discussed somewhere in this thread, but if I rewire so that the fog lights can be on by themselves—without headlights—will they be effective as "real" fog lights in a dense, pea soup, 34-car pile-up kind of fog?

If you spliced into the smaller of the 2 wires from the ACC relay, then you can turn the fog light off by turning the fog light switch off. Located next to where u turn on the headlights.

My next question:
Can now I install a second set of Fog lights?
Run wires to a different switch?
I did get the switch/dsc that has a fog light switch on it. Wonder how hard it is to use that one?
Is it legal to have 2 sets of fog lights?
Would want a yellow set but not sure if LEDs or not.
any comments on that?

I just did this on the weekend to hopefully pass DRL here in Canada, will find out tonight if it passes. It is so simple thx to Magnesium and Omicron you guys rock!

The whole thing took 10 min. if that. I attached it to the ACC using a 22-18 gauge Quick Splice and caped the other end of the brown wire so it wouldn't short on anything. I think it is even easier doing it this way and don't have to waste time splicing wires or anything. Worked like a charm!!

Hope I pass the inspection tonight :)

That's way too much in my pinion. You can run wires from the ACC to your switch, that way you can turn on and off your fogs whenever you wanted to.

You probably didn't disconnect your battery before you did the mod or you hooked up the wrong wire. Either way, I would double check your wiring or put it back to stock and start over before you turn your fogs back on. It may blow the fuse again if you hooked it up wrong.
Let us know how you make out.

You should tap to the end coming from the fuse box.

You must be doing a different mod than I did. I attached the jumper wire to the larger green/white wire. This wire lets me use fog lights with parking light, lowbeams, and high beams but they do not work with lights in the off position. which is how I wanted it. There are a couple of different variations.

I done the same thing and mine already had the wires run.. When I bought my foglights the dealership told me that they are already wired just install and plug in..Other than that I don't know because I had the dealership install them for me. I am good friends with one of the guys and they didn't charge me much to install. So, I let them so I would not have to fool with pulling the nose piece off.

I have taken my psgr. side fog off and put it back on without removing the bumper, but I am not sure to answer your question. An install could be different. and the driver side has the oil cooler right behind it. crank the wheels both directions and take a look.


Isn't there a bracket or something that needs installed also?

Nevermind... I found the post #214 by Stealth which lead me to a search for "Canadian fog light rewire" and I found all the info I needed. It works now.

One needs to do the OMICRON method + STEALTH method to make it work for Canadian cars.

I also cleaned the air cabin filters too while I was at it hehehehe.

You actually don't need to remove the glovebox to access the DRL module connector. It's within reach if you look under the footwell of the passenger side as I realized. When I removed the glove box, there is a BLACK BOX MODULE in front of the DRL. To gain access to the DRL, one would actually have to remove the black module first if you were going through the glovebox. I looked underneath, and realized that the DRL module connectors are accessible just from the bottom. No need to remove glove box.

This maybe only applicable to Canadian models? I'm not sure what that black box module is.

Blame the regulators in the USA and Canada.
They mandate that any front lights ( other than marker lights) must only come on IF the low beams are on too. They are lumped together sa "driving lights".

Yes, this totally defeats the purpose of fog lights.

If anybody wants the appropriate pages from the Mazda RX-8 2004 Wiring Manual faxed to them, send $5 to my Paypal account..
I will fax anywhere in N.America for that..

If you need this email me at:
maurice@harddata.com

Even seen a Dodge SX2.0 (new name for the Neon)? They have their fog lights as DRL here in Canada!!

Im not sure if its a "stock only or illegal" thing, but whatever.

I went to do this with my 09. Seems I have the same wire colors, same fuse box and everything but it would not work. I cut the brown wire and tried the ACC method first, but the fogs only came on when the headlights still.

Then I tried MMs method and tried the tail light relay and fuse. neither worked. Any reason why it would not work on an 09? Like I said, seems like I have the same fuse box and wiring. Only thing I can think of is it might not be the brown wire on mine, but. I used the first wire on the right side of the relay, out of the four available.

The wire was a different gauge than the ACC wire so maybe that indicates a change.

Basically, I attempted to do this mod all day today. Every time I would try and test the fog lights my ignition fuse would blow out. I made extra sure both sides were taped with tons of electrical tape, and I triple checked I had spliced the right wires. After the third blown ignition fuse, I restored everything to normal and everything works fine, with the exception of my fogs because I have the wire detached and taped (I bought some taps in case I have to put it back together). Any ideas what I could be doing wrong? I know this is useless without pics, but I didn't have time to take any when I had the mod installed. because I needed to get my windows up before the thunderstorm rolled in. I used the vampire clip method.

Thanks guys

EDIT: I think I figured it out. I cut the right wire, and was splicing to the right wire, but I think I was splicing in the wrong end of the fog wire (the one from the harness) into the ACC wire. This would probably explain all of the blown fuses, because although i don't know what that mistake would do, it probably wouldn't do anything nice to the fuse box. Lesson learned, always double check. My stupidity knows no bounds.

Edit2: Fixed it this morning first thing, mod works great, thanks for the great DIY (Even if I did a piss poor job at following it)

Simple mod once i figured out i was suppose to connect the brown wire coming from the fuse to the small red/white wire. Only blew out one ignition fuse.

This has already been covered earlier, I am not trying to take all the credit for this. I'm just trying to make it simple in only few steps with pictures.

This set up will let you use the fogs independently through the fog switch. You could have the fogs by their self, with the parking and side lights or with the headlights. You control them by the switch. Also you could leave the switch ON and turn off the car, fogs will have no power.


So, here it goes... Five steps....

1. Disconnect the negative terminal off of your battery.


2. Remove the fuse box cover, turn it around and locate the FOG Relay and ACC Relay.

3. There are 4 tabs on top of the fuse panel, undo the 4 tabs shown on the picture to get access underneath the fuse panel.

http://i290.photobucket.com/albums/ll248/ivothegreat/PIC2.jpg

4. Cut the brown wire coming out of the FOG's Relay enough to rich the thicker White with Red stripe wire.

http://i290.photobucket.com/albums/ll248/ivothegreat/PIC3.jpg

5. Locate the Thicker White with Red stripe wire from the ACC Relay and connect the brown wire coming from the FOG Reray with a wiretap. Make sure to cap the other end of the brown wire as we don't need it any more.

I tried to make it as simple as I could to understand, but once you open the fuse box you will understand everything.

You cut ONLY the brown wire

BG-8
08-16-2010, 03:28 PM
sorry, looks like I missed the party...

THE ONLY WIRE THAT GETS CUT IN TWO IS THE BROWN

REMOVE ONLY SOME OF THE WIRE RUBBER INSULATION OF THE THICKER WHITE/RED STRIPE (DO NOT CUT IT IN TWO PIECES) TO MAKE GOOD CONNECTION BETWEEN THE BROWN AND WHITE/RED STRIPE WIRES IN THE WIRETAP.

Question ... I used to be able to turn on my hids and fogs even if the cars off. Now I'm only able to turn on my hids but not my fogs when the car iis off. is there any way to fix this ? I know this is stupid but I like everything to be "perfect" and I hate being able to turn on only my hids when the car is off.

BG-8
08-16-2010, 04:59 PM
OK... the Fogs are wired to the ACC Relay. Which means you could only have power/electricity to the fog lights when you turn the key to ACC (turn the key once). You could wire the fogs differently so you have power all the time, even if the car is off, but there will be no beeper to warn you so you don't leave them ON (like the one for the headlights).

In my opinion, the best way is through the ACC Relay. Why would you need to turn them ON when the car is OFF? Plus you could still turn them ON if the car is OFF, just turn the key once to ACC and Voila... ;)

Rotary-RX8
08-16-2010, 07:21 PM
Yea but I wanted to be able to turn them on without the key veing turned at all. Oh well !! If you guys have it that way then I guess ill leave it.

So I went to do this mod and I don't have a brown wire going to my fogs relay or the Black and red wire going to the tail relay.... only difference I can think of is I'm in canada and DRL's are mandatory. Can anyone comment on this? I want my fogs to come on when I have the park lights on.

RotaryMachineRx
08-18-2010, 07:27 PM
Okay took a closer look, found the red/black wire going to the Tail FUSE not relay and I have a black/white wire going where the brown wire is located in MM's pictures but it is jumpered to the Head Low R fuse ... will the white/black wire be the same as the brown one (just cut it betweem the head fuse and fog relay) or do I need to do something different here? Here are some pictures....

RotaryMachineRx
08-18-2010, 07:47 PM
Well I'm gonna go ahead and try this out... I also couldnt find my heat shrink wrap so I'm gonna have to use good ole fashioned electrical tape until tomorrow when the stores are open again.

Edit: Found my shrink wrap!

RotaryMachineRx
08-18-2010, 09:03 PM
So I did this mod by soldering the black/white wire that was jumpered between the fog relay and Head Low R fuse to the black/red tail fuse wire. After reattaching everything the verdict is.... Nothing Happened. Does anyone have any insight on this? My fogs still turn on only with my headlights.

Footman
08-19-2010, 02:00 PM
You Canadians are all forgetting an extra step that needs to be done in the DRL module. Doing that step will enable you to turn your fog lights on even when your engine is off. It will only require the key be in the ACC position to turn on fogs.

Hi, I don't have fog light for awhile now for some reason, today I replace new fog bulbs, re-connect the wire to original, check the relay fuse, fog fuse they are all good but, there still no light. Anybody has any idea why? with the car on running, I turn all lights and try to touch the bare BROWN wire to other wire and still no luck, thanks for any helpful hint.

I was doing it Omicron's way.....ran the brown wire from the fogs to the thin red and white wire from ACC. When i crimped together with blue connector nothing happened. I tried just wrapping it, thinking I wasn't getting a good connection. Negative. The headlights appeared to be strobbing though. Any ideas. Thanks in advanced!!!

OK, I finally did this using the Omicron method (using the thing red and white wire). The only variation was that I used a T-tap on the white/red wire and male and female disconnects on the two ends of the brown wire, so that if I want to go back the way it was, I just have to unplug and plug.

Woah, stop right there! Get a fluke or a test light first!!!!!!!!!!

Check the voltages and go from there. A DIY is good for a lot of info, but maybe a canook can chime in. You never stated a year/options, etc, could be some unknown variations in the mix, never know.

Better safe than sorry!

I didnt check my voltages when i did mine and ive done it like a year and a half ago. Everything is perfectly fine.

So basically you connect the black/white wire (brown on US cars) to the red/black wire.

The black/white is the wire that gets cut correct?

no clue man I did the black/white wire way I showed and I havent even touched the DRL module so technically I havent even done this mod. But all I know is the way I did it should turn the fogs on with the parking lights and I believe once I mess with the DRL's they will no longer be on as soon as the car is started.

Ok, so I did this mod tonight, I did mess up and it probably took way longer than it should. But After I cut the brown wire, I taped off the wire closest to the relay and then started using the other half of the brown wire to the (first) the black/red wire and my fogs would not turn on. 2nd I used the wire and connected it to the white/red wire and still no fog lights.


I then untaped the brown wire closest to the relay. Since I made a mistake and made the wire to short, I had to come up with a different way to make it work, so I cut the ACC relay (thin white/red wire and connected it to my brown wire and voila it worked, now my fogs turn on intedependently of the headlights and the parking lights which is awesome.

OK Now! I also was installing my HID Fogs from VVME. I got all the way to hooking up the Ballast and they are the 35w Kit. When I turn on my Fogs I hear a sound like its getting power but no lights come on. I plug back in my original fog light bulbs and they work fine. Could this be because I have the Fog Wire connected to the ACC relay and its too much power? If so How can I fix that?

:dunno:

I am hoping someone can help me with this mod. I am new to this site, and have read everything I can about it. My car is a 2004 and is a Canadian version. I have the daytime running lights on mine.

Under my fuse box relay, the wire is NOT brown. It is also NOT the brown with white stripe that is mentioned on here by another Canadian member (I think because the wire color changed again in 2006). Can anyone help me do this mod? I have also un-plugged my daytime running light relay that is behind the glovebox, but have not cut any wires on it yet.

Any help would be greatly appreciated.
