jhnyblayze asked:


I purchased a trailer that has electric trailer brakes. I don’t know how to hook up the brakes. The 7 way plug I purchased has only one wire for the electric brakes (blue). Each hub on the trailer (there are 4 of them) has 2 wires coming out the back side. I assume one is the power and one a ground. Do I just splice all the power wire and all the ground wires together and attach them to the power and ground on the plug? Help me out!
