dark... are you sure you had the WINJET fogs? My stuff doesnt match up with the oem instructions AT ALL! its all wonkey! they may have simply shipped the wrong wiring harness. i am contacting the company i ordered through to fix the issue. I will provide further details on the situation.
Would be nice if they came with instructions.
EDIT: I have them installed... not exactly 100% satisfied with the results due to how the fog lights function... i will have a full writeup later.
Further edit... almost dissatisfied enough to take it all out and return it... almost, but not today.
Basically, the only OEM instructions i followed were the ones that show you how to cut and mount the fog lights on the bumper. When i got to the inside, all you have to do is ground the black wire (black wires are almost always ground so it was a safe bet) Set the switch, Run the positive wire (the one with the black sheath around it and the actual wire is blue with grey stripe) through one of the rubber grommets to the outside up over the fender and back to the fog light wiring harness. I followed the oem fog light harness routing instructions. Do NOT cut any existing wiring on the E. This is basically a standalone system.
back to the inside. Plug the single pin wire into the fusebox (sorry, this is only the SECOND thing you do following the oem instructions) mount the relay switch (which i am not sure what purpose it serves, more on this later) plug the 5 pin plug into the switch, replace all plastic parts you have done, mount the bumper while plugging the lights into the fog light assembly. and boom, you're ready to go.
What i dont like about this system are as follows:
1. Does not use OEM wiring harness.
2. lights can function no matter if your low beams are on or off, your car is on or off, or even if your high beams are on. (this is why i am not sure what the relay switch really does)
3. the switch that comes with it is a little wonkey. sometimes it works fine, but sometimes it wont stay on, or turn off properly (engage/disengage properly). To fix this while it wont engage (stays disengaged) i have to push it slightly to the side to get something in the switch to reset.
Other than those three major flaws, they work. They just dont enjoy the full functionality of the OEM fog lights. if i had to do it over again, i would purchase the OEM fog lights period end of statement. The only reason i am not taking them out and returning them is that i am lazy and i dont feel like pulling the bumper back off and taking it all out... putting the bumper and everything back... waiting a week and a half until the OEMs come in and doing it all over again (minus modifying the bumper of course). That said... they look great, and with a little bit of manipulation they are (somewhat, obviously not fully) functional.
if anybody has a workaround that wouldnt involve cutting more than 1 wire to make them at least switched (turn off when the car is off) let me know. I dont really want to fabricate a full up oem style wiring harness.
Again... spend the extra money on the OEM fog lights.
