If this is a pick-up there should are ready be brake control wires in the rear. If it is a SUV then lift up the flooring in the rear it will be there. The wires are already ran. You'll find a plug back there. If you can't find it check owner's manual or with dealer.

If don't have it.hmmm take a volt mater or light and put it on each wire ever time you push on the brake one of the wires will go from nothing to 12 volts or light up your little light.
