Expert Reply:
I would be happy to identify the functions of the wires on your Tekonsha Prodigy P2 Trailer Brake Controller # 90885.
The wire functions are as follows:
Black wire is to be connected to vehicle battery with 30 amp circuit breaker like the # PK54230.
White wire to ground
Blue wire to trailer brake wire
Red wire to cold side of brake pedal switch which only has power when brakes are applied.
To determine the functions of your vehicle pigtail you will need a circuit tester like the # PTW2993.
I included a video of the # 90885 for you to take a look at.
