I have a new tow vehicle, 2004 Ram 1500 quad cab with a 5.7 hemi, it has the towing package with a wiring harness included. Has anyone ever installed a brake controller, and how involved was it. It seems to me about all there is to it is plugging in the wiring harness and putting in a couple of screws. Let me hear from you please, I am thinking about doing this myself. I am pretty mechanical.
