I have a 16 XLT that has only towing prep. I have found the harness for brake controller and dug it out from rear part of "drivers side cubby hole". My question is Im going from a 4 way flat to 7 round and have gotten the Hopkins Multi tow adapter. I did see on vehicle that the blue brake line is underneath near 4 way connector that is capped. What would the purple and black hook up to from Hopkins Unit to Vehicle? Whiye would obviously screw to frame for ground. Am i missing anything here. I have ordered brake control harness and also the brake controller. What do I need to do for the 12v to charge trailer battery as well. Thanks for the help!
