The vehicle wire that you want to connect to the red input signal lead for a brake controller like the Prodigy P2 # 90885 is the wire from the cold side of the brake light switch. The switch is usually located at the top of the brake pedal and the wire to the cold side of the switch is the one that will carry a signal only when you press the brake pedal.

A circuit tester like # PTW2993 makes it easier to identify the correct wire.

The controller black wire brings 12V power from the battery (through a circuit breaker) to operate the controller; the white wire is ground and connects to the battery negative terminal; the blue wire is the controller's output signal that is to be routed to the vehicle 7-way.

Answer 5

The weight of the weight distribution hitch will actually not count towards the tongue weight of your trailer. So when you use the #BXW0356 you were looking at its 100lbs will not take away from the 350lb tongue weight rating of the trailer hitch…
