Does anyone have the shift interlock wiring diagram? The shift interlock switch operates off the same brake pedal switch as the brake lights or the cruise control brake pedal switch? Theres a relay in the engine compartment is it 85-86 for the brakes lights or shift interlock? Im trying to find out why the shiftlock mechanism stopped functioning. Its a green and grey wire from one of the brake pedal switches to the shift interlock only im not sure if there is a fuse or relay in between or after the pedal switch to test for power and ground or to jumper wire, power probe. Im trying to see if the brake pedal switch is bad or the shiftlock electromagnetic mechanism.
