Using a standard ring connector, we tapped into the factory main relay on the battery side. then ran directly to a 20 amp circuit breaker. from these we used standard double jacketed brake wire and connected to the breaker. This 12 volt power wire is ran both to the rear of the truck, and through the firewall, into the dash area to power the controller. The other wire inside the double jacketed cable we use for the brake control power to the trailer, so it simply goes directly from the rear trailer connector, to the blue wire on the brake control.
We tapped into the Green wire for the brake light signal (red wire on the controller) - to be sure, use a 12 volt test to confirm this wire comes on when you press the brakes.
