I am wondering if anyone knows where the stock fog light wiring is for 2000-2006 Suburbans and Tahoes. I am looking to hook the stock ones up but cannot find the wiring anywhere. Thanks.

 

am in the same boat as you I can not find anything about the fog lights but on an 07 trailblazer I put them on but where do you wire it

 

Hi cbe295,

I found this from another forum:

"I bought the kit from GM. I followed the intructions exactly. First I installed the cargo/fog lamp switch. Then removed the old valance. And installed the new valance. Installed the fog lights and then the fog lamp relay in the BEC.

The next step was a little confusing. Hooking up the wiring harness. It stated I had to pull the cover off the BEC, lift up the BEC panel and hook up the single wire to to terminal D6 on the lighting block. The diagram showed one thing and the instructions are stating D6. Once I confirmed which terminal was D6 I found wires already hooked up here. Two purple wires. I remembered seeing a plug taped up to the wiring harness on the drivers side near the radiator core support. So I checked the Passenger side and found another plug with the same purple wire. (Note-the plugs also have a black wire going to them-the ground). So it was safe to say, my truck was already pre-wired for foglights!!

The last step is to have the BEC programmed to "see" the foglight circuit. But guess what? It also was complete and the test of the fog lights was sucessful.

So in short, before you go through all the trouble to open the BEC panel, check and see if your truck is already pre-wired for foglights."

Maybe this helps...
