DIY: Fog Light Rewire
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.
Did the Omicron mod over the weekend. I didn't get fancy though - just used tape to wrap everything...
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.

did this mod, like it alot,using brown taped into small white/red wire, but problem is when I park and listen to music, the light is also on, is there a way to re-wire so only light is on when you turn the car on? did I miss a thing? thanks.
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?
just did this today and blew a fuse.....car wouldnt start.....it took me 2 hrs to figure out witch one.........it was a 15 for the ignition..........just in case it happens to anyone else.............but the car looks sweet now.......thanks everyone
fog light on/off
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
Thx again guys!

**UPDATE**
Had the inspection last night for Canadian DRL and passed with no problems
Mazda quoted me $204.99+tax to put in a DRL module. HAHA what a joke!
