asked by: Bill
Helpful Expert Reply:
Yes, one of the few consistencies in trailer-related wiring is that all trailer brake controllers such as the Prodigy P3 # 90195 use the same 4 wire colors for specific functions.
The controller's Black wire connects to the vehicle battery via a 20- or 30-amp breaker for operating power; the White wire is ground; the Red wire takes in the brake switch signal from the cold side of the brake light switch and the Blue wire delivers the controller output signal to the 7-way socket on the vehicle.
This wiring setup is shown in detail in the linked article and photo.
