Does a Brake Controller Plug Into a 2007 Chevy Silverado New Body or Does it Hardwire In

Question:

I have a 2007 Silverado ext cab LT 4x4 new style, not classic. I bought a Tekonsha P3 with a #3015 adaptor. Will this adaptor work for my truck? I get the feeling in may be for the classic truck

The 2007 Chevy Silverado New Body does not use a harness to plug in a brake controller. That stopped in 2006 and 2007 Classic models. Instead your truck has a tow package wire bundle under the dash, to the left of the steering column, held together with white tape.

You can keep the harness that you have and just cut off the end that would normally plug into the truck. Brake controller white goes to truck white for ground. Controller black goes to truck red for 12 volt power. Controller blue goes to truck dark blue for output to the trailer brakes. And controller red goes to truck light blue or orange for input from the brake switch.

I have included a link to a video and help article that show and explain the installation for you. There may be some additional connections that will need to be made under the hood to make everything fully functional. This is also covered in the article.
