Great DIY's from both guys and looks awesome,I just might do this (mod)
And to some of new guys!! all I did was Google (rear fog light for an RX8 )and it
took me right here and showed me how to do it. That was easy
Blah...not even worth all that trouble. Wired mine straight up to rear tails and have never needed or wanted a button. Tails on....rotor fog lamp on. Good to go. But regardless, nice write up.
For this can you have it run as both running light and brake light.
Meaning when the parking lights are on the 6 Watt Filament is on with the lights and when you hit the brakes the 21 Watt Filament lights up?
Any help on the colours of the wires would help. Pictures if available.
hey great post! I tried doing it but I just ran into one problem. I have a blue cable coming off of the switch harness!! I don't know what to do with it. the rear fog is not turning on
Thanks for the great DIY! I can't read Japanese
I did everything the same (including the same MPV switch mod) with exception of the rear bumper cover that I didn't need since I have an Odula rear cover
Picture of the wire routing (step #15 in the install manual):
On to the fuse box. This is step #16 & #17. On my car, I don't have BOSE so there was an empty slot that was perfect. Just take the yellow wire from the bundle and slip it into the back side of the fuse box. It already has a terminal pin on it so it just clicks into place and locks in. Install the provided 10 amp fuse after you hooked up the yellow wire. The yellow wire is considered pin #30 on a relay and it must be fused. (no that is not my cheezy white ground wire, the car had a dealer installed alarm and I had them take it out. They left the ground wire there. I think I remember removing it) See the next two pics:
If you have BOSE, good for you (or bad depending on how you look at it). You will probably just have to use a tap or one of those add a fuse fuse holder you can get.
Now we are at step #18 of the instruction manual, you need to mount the fog light relay. Just follow the illustration. I think I ended up using zipties here.
Ok now steps #19-24. You are going to have a lot of excess wire on this main fog light harness we have been working with. Remember this is for a RHD vehicle so the wires had to cross over to the other side but our is LHD so no need. You can cut the excess or just bundle them up neatly. That is what I did. If your still following the provided install manual, you can see them wanting you to remove the instrument cluster and insert the other RED wire coming off the fog light relay into one of the connectors. This is to have the rear fog light indicator light up in the instrument cluster whenever the rear fog light is on. I checked the wiring diagram and the pin slot is free, I even shined a light on the instrument cluster and you can see there is a spot and even the indicator on the existing cluster. So I went ahead and hooked this wire up, BUT it did not work! I think the LED is missing on the circuit board at least that is what it looked like to me. I didn't want to take the cluster apart just to check. Just so you know, my vehicle is a 2009 Touring Model. You may want to hook up this wire just to see if your cluster has the LED as it would be pretty cool if the indicator worked. If you don't hook this wire up, make sure you wrap this red wire up so as it does not touch anything and short out. This is a power wire lead (pin #87) and is the same circuit that goes directly to the rear fog light. Another option would be to cut it out completely from the fog light relay if your sure your not going to use it.
Step #25. Now your going to have to pull out one of the blanks switch panels from the dash. This is a hard part. They have a clip on the top and the bottom and you need to press them to be able to push the blank switch out from behind. You need to remove the middle dash panel (the one located below steering wheel) for access. Good luck! It's tough. You might have to unclip some wire harness bundles that are in the way. I removed the blank panel all the way to the right, it's the easiest to access.
Now we are going to work on the provided fog light switch short harness.
Step #26 Is for the combined DSC/Fog light switch. You didn't order this one right? So we are using the next step.
Step #27 (Ok my memory is a little fuzzy here so someone correct me if I'm wrong)
In the install guide, they are showing you connector A2. (The rear fog light switch connector is A1). If I recall correctly, there is no place to plug the A2 connector into our US wiring. So what I did was cut this connector off.
There are a total of four wires going into our switch. The black wire is ground (which we will hook up later). The blue wire is the "switch to ground". It completes the circuit to the black ground wire, which provides the ground for our fog light relay. This would be pin #86. The other two wires are for illumination. It is for the little light bulb in the switch that turns on whenever the parking lights are on. Again I couldnt find a connector to plug into so we are going to tap into the illumination wires at the DSC switch (right next to it). If you don't have DSC, you should be able to tap into the dimmer switch the next one over. (GO TO NEXT POST)
Here is a shot of the short harness that connects to the rear fog light switch:
Hi i know this was awhile ago but do you know which pin you tapped into for the rear fog on the instrument cluster?
