It does not appear that the harness on the trailer has been replaced. I only have a 5 wire. Green,yellow,black,brown and white how do you power the brakes

Expert Reply:
If you trailer has a 7-way on it with 5 wires ran to it and the trailer has brakes the 5th circuit (black wire) would be the circuit that is carrying the brake voltage. You will need to install a 7-way and brake controller on your tow vehicle to allow the brakes of the trailer to be activated. I attached a couple help articles that cover installing brake controllers and their functions.
For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. This will be the last brake controller you buy. It can easily be transferred to future vehicles as well.
