This part has 4 wires coming out the back. I need to know what each color represents. Colors are Blue, White, Red, and Black. Thanks.

The blue wire carries the brake controller output voltage, the white wire provides the ground connection and is usually ran to the negative battery terminal, the black wire is the 12-volt power supply, and the red wire typically connects to the brake stoplight switch located above the brake pedal. This connection activates the trailer brakes once the brake pedal is applied.
