PIAA Wiring
Best Regards,
Here’s how to install PIAA fog lights on a Z06 using OEM hardware. This tip should also work on a FRC as well.
Parts list:
2- bolts part # 11514623
2- nuts part# 10281487
1- switch part# 12135155
1- lt fog lamp part# 10438855
1- rt fog lamp part# 10438856
You may want to fabricate your own brackets or find some other way to mount the fog lights since you cannot buy just the brackets alone. The factory lamps themselves are pretty pricey and you will be tossing the lights out anyways.
1. Pry off the trunk release switch and replace with the new fog light/trunk release switch.
2. Raise the headlights. Disconnect the battery.
3. Locate the fuse box next to the battery. Remove the fuse cover and locate the fog light relay. It should be #39. Remove the nut that holds the fuse block. On the sides of the fuse panel, there are 4 tabs that hold the fuse block down. Carefully pry the tabs away and at the same time pull up on the fuse block.
4. Under the #39 relay you will see a thin purple wire. Take wire harness from the PIAA lights and locate the on/off switch and cut it off. Tape up the thin black wire. Take the thin white wire from the harness and splice it in with the purple wire under the #39 relay.
5. Connect the thick white wire on the harness to the auxiliary 12v connection on the fuse block. Connect the thick black wire to a grounding point. There is one right on the frame rail next to the hood strut.
6. Route the wire harness toward the front of the car. You may want to use black split wire loom to cover the harness and give it a factory look.
7. Remove the fog lights from the bracket. Mount the PIAA lights to the factory fog light bracket by swiveling the base on the PIAA light 90 degrees and bolting it to the bracket.
8. Remove the headlight bezel. There are three screws holding it in place.
9. Locate the factory mounting point on the frame. You should see a rectangular cutout with a small hexagonal opening below it.
10. Push the nut through the hexagonal opening and hang the light assembly off the rectangular opening. Now bolt it down. Don’t worry, when you bolt the lights down, the sleeve on the nut will compress, holding it in the frame.
11. Connect the lights, reconnect the battery and aim the lights.
You can use PIAA wiring harness and factory fog light switch. Just hook PIAA wiring harness on/off relay switch to purple wire on factory fog light socket.
When factory fog light switch is pushed on, purple wire on factory fog light socket will be powered up.
Good luck with install:cheers:
