I have a Chevy Silverado 2007 2500HD Classic.
I made a trailer:
I bought a brake controller. My truck manual mentions that I have a harness for this controller, and says to go to a dealer to install one.
I would prefer to do it DIY, so, can anyone tell me where to find that harness.
Also, there is no power on the auxiliary power pin going to the trailer, is that because I have to wire it along with the controller?
thanks
