Curly,
The plug on the top of the IP is the rack position sensor, nothing to do with
idle. It has a locking ring that needs to be turned to allow removal.
There is a small two pin connector at the back of the IP, between IP and cruise
control actuator, which is for idle. Pinch to release.

No, that one is for diagnostics, specifically setting the injection
timing with the dynamic tool.
The one for the idle speed/tach is on the rear of the engine reading
off the flywheel.

Interesting. Thanks again. We have a 87 124 300D that has a
completely wacko idle. Everything
