I have a hard time using the search engine on here so i find it easier to start a new post.

i recently bought a SS S/C bodykit, and it has the stock fogs, the guy i got it from thinks he may also have the interor trim so i will have the button, now if i went to my local GM dealer and asked for the wiring harness for the fogs lights where would they plug into?

 

The foglights are done through the BCM from factory. Not sure if you're going to get that to work like stock. You'll need to do your own wiring...etc from them and add a custom switch if you want to control it from the interior.

You could just have them wired to a relay to come on whenever the lows are on.
