Ok guys, i have a question. I just bought a new 7x16 trailer with brakes and have to wire them. There is a white and black wire from the axle that i need to figure out which one goes to the blue wire on the controller. If it is like the rest then the black is the power wire and the white is ground. Can someone help me on this?

do you mean the wires that come out of the backing plates of each drum?
if so, color doesnt matter they work off resitance not voltage.the wires are attached to magnets inside the drums that activate the brakes.

if you have any other questions let me know.
