I am putting in a trailer brake controler. I found the wires to hook the plug to, but where do they come out at the front of the truck? Are they under the dash?


Look at the harness on the back side of the fuse box under the hood. Pull the fuse cover and the fuse box housing. You will probably have to remove the fender brace. They usually run the wires to connect to in the harness and bend them back into the wrap. Should be orange and blue. You will have to splice into them under the hood and run wires into the cab along with a GOOD ground and the drake switch and a hot fused wire. Look at the owners manual and see if fuse post 1 and fuse post 2 are connected. If not, one will feed to the brake controller and the other to 12 volt power to the trailer... Blue brake and orange to trailer power.
Also look at http://www.etrailer.com/faq-wiring.aspx. Full of useful info.

2008 GMC C5500 factory wired for trailer harness (7 pin). I just purchased brake controller and am trying to find where the controller harness plugs into the truck harness. Looking under the dash. Plug...


You are probably going to find four wires together that do not have a plug on them. There should also be a tag taped on the wires showing that it is for the trailer. You will have to put a plug or some kind of connection on those wires.

I'm trying to install a Tekonsha trailer brakes and need the wiring diagram


The controller should have wiring diagrams with it. Also try http://www.etrailer.com/faq-wiring.aspx. The truck should have a harness that plugs into the factory harness under the dash. The harness paperwork will describe where it plugs into and what wires go where along with fuse location. If you don't hav the harness, you can get it from the dealer or the site listed above.

Trailer brakes lights dont work on my 2001 gmc 2500hd


Do you have brake lights on truck? Is this a new hook-up or has it been hooked up before & worked fine? If your brake lights on truck are one color (red) and your turn signals are another (amber) you will need to buy & connect a small converter that goes in harness to plug in order to separate the 2. Instructions with converter are pretty simple.

Trailer brake controller problem


I found the problem. Talking with a technician from the controller company, we determined that it was a fuse problem. I found that the fuse to the CHMSL was blown.
