4 way electric brake connector
I need to tow a larger trailer then I normally due I have a 1999 Dodge Durango. The trailer I will be towing has breaks so I would like to hook up the brake controller. The Durango that I own has the trailer tow kit and has a 7 pin connector attached in the bumber. The kit also came with with a harness to ease the installation of the electric trailer break controller. The harnes plugs in under the instrument panel and has 4 wires coming out of it. Here is my ignorance, what else do I need to make the breaks work. What am I attaching these four wires to? And where do they plug into on the trailer?
