    I've replaced the throttle pedal in my M54 car. It's an integral unit. You're going to need the ECV from the donor car (prolly gonna need this in any case). New mounting plate with wiring harness and new pedal. The throttle body is actuated by the ECU receiving signals from the potentiometer in the pedal assembly.

    You will need to make a harness for the pedal that connects to the DME.
