    First Name:
    2012 Toyota Tundra 4.6l Double Cab
    2012 Tundra 4.6l no towing package, originally with 4-pin connector

    I'm installing a Tekonsha P3 and used the 3040-p harness to connect the controller to factory harness located behind the left kick panel. HOWEVER, the blue and black wires for power and trailer brakes do NOT make their way to the back of the truck where the original 4 way harness is located. Does anyone know where the blue and black wires go to off of the factory harness?
