Trailer brake controllers such as the Prodigy P3 # 90195 require a brake light switch signal to trigger the controller's output to the trailer brakes. The best way to access a brakes-only signal is at the COLD side of a vehicle's brake light switch; this is the wire that carries voltage ONLY when the pedal is pressed and at no other time. The pedal position sensor will not work.

You will need to access a brake-light-only signal at the car's BCM (body control module) which is just above the driver's left knee. Find the black X4 connector and look for the white wire in position 11. This will give you the correct signal to connect at the controller's RED input wire.
