Hi

needing some help, I have installed a Mopar seven-way trailer connector. I have ran the electric brake wire to the cab, and purchased a brake controller. Now I assum the Blue wire out of the controller goes to the blue wire that runs back to the trailer plug. but the instructions that came with the controller, well in a word are terrible, I have no idea what to do with the Black, Red, and White wires that it has. I have some basic electrical assumptions in that one is hot, one is ground, and the other must go to something with the brakes. Thanks for any help.

 

Does this help?

You can run a search on the cummins portion, this is a heavily addressed issue. does your truck have a hook up already like this by the parking brake?
