Re: 2014 JGC Brake Controller DIY
I just purchased a 2014 JGC , diesel with a tow package. I found a small harness in the glove box that I figure is for the brake controller. The dealer told me that they must instal the brake controller so they can program the ecu, is this true? If not what kind of brake control do I buy? What is a P3 and Directlink that everyone is talking about, forgive my stupidity I just don't get what to do.
