I don't know if this is the place to post this, but I am pulling this with my 70 GMC, so....

I borrowed a car trailer yesterday. I needed to hook up a plug on the trailer, the plug that was on it didn't include the trailer brakes. He hadn't ever used the brakes on the trailer. I should say he hadn't had the trailer that long. Anyway, their are two wires for the brakes on the trailer (brakes on only one axle), a black one and a white one. I'm not sure what wire goes to what, and I don't want to hook something up wrong. I would guess the white is ground and the black is hot. Any thoughts?
