Wiring Configuration for Tekonsha Prodigy P3 Trailer Brake Controller 90195
Question:
Hello, I have a question about the Tekonsha Prodigy P3 Electronic Brake Controller. I wanted to confirm that the expected definitions are as follows: 12V Power: 12VDC input Stop light: Signal indicating braking. It is either 0V or 12V. Its an input Ground: Chassis Ground Trailer Brakes: The output voltage signal that is proportional to how hard the brakes is applied. This is the signal we would feed to the trailer to control the brake pump.

The Prodigy P3 trailer brake controller uses a 4-wire hookup. The white wire is to be grounded to the battery negative terminal; the black power wire connects to the battery hot terminal through a circuit breaker; the red wire takes in the brake light signal from the cold side of the brake light switch and is used to trigger the P3 to send out a brake signal on the blue wire.
The red wire will carry an on-or-off signal; the actual degree of braking power sent to the trailer connector on the blue output wire depends on the power setting and the degree of deceleration in the tow vehicle. Proportional brake controllers like the Prodigy P3 generate their output signal in proportion to the rate the tow vehicle slows down, which keep the vehicle and trailer more in sync with each other for less of the tug-of-war feeling between truck and trailer.
To use the P3 with an electric-over-hydraulic (EOH) brake actuator on the trailer be sure to select EOH mode from the menu screen.
