Ok guys I plan on installing the OEM fog lights on my truck. I have the switch, the two lights and the relay. What i need to know is where EXACTLY did you other guys that did this find the harness that is supposedly already there. From what im gathering it is somwhere up around the bumper and the front of the frame. Pictures would be great if anyone had them.:D

If it is there, it will be wire tied to the radiator core just behind the grill. That's where mine was.;)

Ok thanks man I honestly didnt even crawl under to look yet, I was gonna do it when I change my oil but im sorta under the weather right now:(. So thatll give me a good place to start.

I don't have fogs yet but when I put my Super Scoop in I found a wiring harness connector close to the horn on the passenger's side. Don't know if this will help.

Yea that might help.....I looked all over that truck tonight and couldnt find anything. I guess ill have to look closer around the horn. I saw it but its so damn tight up front and all the plastic stuff is really anoying when your trying to find something. :mad: O yea and if anyone has pics of this location that might really help me out.:D

I Would Like To Know Also If The Wiring Is There I Am Also Planning On Putting Some Fog Lights, Well Not Really Fog Lihts More Like Offroad Lights. Hey Jd4440 Where Did You Get The Switch And The Relay? Any Parts Store Or Dealer?

I actually got everything except the relay through a member here on the market place. I was gonna stop at the dealer on Monday to see about a relay.

My 07 classic was not equipped with fogs and it did NOT have the fog wiring harness installed. However, GM sells a fog light kit for both GMC and Chevy that includes everything you need to install the factory fogs for around $250. This kit includes the wiring harness, bumper cover, lights, dash switch, etc. along with a very detailed set of instructions showing exactly how to tie the harness into the truck fuse box. Buying all the parts piece meal was more expensive and did not get you the instructions. And before someone asks, no I don't still have those instructions.

i found mine on the drivers side sitting on top of the radiator suport just behind the front fender where the fog lights would go, it was routed up and over and just hanging there it if you know what i mean,
