I am curious if this electrical breakdown will require a new or rebuilt actuator or could it be just the wiring. I have a new engine wiring harness, but now am being told I need to replace the throttle actuator. Also, the wiring attached to the O2 sensor has disintigrated. I have been told there several wiring harnesses in my vehicle. Are both the O2 sensor and throttle actuator on the same harness? If so, anyone know a part #?

I am basically looking to avoid replacing the throttle actuator.
