I just purchased a 2007 Tahoe LT yesterday and I went to install my trailer brake controller as on previous vehicles. I had no problem wiring the 4 under dash wires for the controller but I can't locate the blue and red wire that is supposed to be located under the hood by the main fuse box. The owners manual says to have your dealer make these connections. I removed the fuse box and didn't see the wires under neath and didn't want the wife to see me gutting her new ride so I put it back together. (On my 2004 Avalanche all I had to do under the hood was install the 30A fuse for the brakes.)

Has anyone wired these 2 wires themselves? If so, which harnes are they located in and were do you connect them. Any help would be greatly appreciated.....pics are worth a thousand words!

 

Hello Heavy:

Look a little deeper into the forum, I asked the same questions and they were answered on a thread called Brake Controller.

Thanks Jason........I appreciate it. Did you have to hook up the "Blue" wire mentioned in the owners manual or just the red/black wire to "Stud 2"?
