Here is the typical brake controller connection method. Red wire to cold terminal of brake switch(cold terminal gets 12v only when brake pedal is pressed). Blue connects to trailer brakes. White is ground, and Black goes to a 12v power source. We offer a wiring adapter, part # 3035-S that would plug into the OEM socket under the dash, and the bare leads on the adapter would wire directly to your controller.
