Wiring for Idle control unit. 1983 380SL
My idle air control unit is not working and I am trying to understand how it is powered. I saw somewhere it should get power on pins 2 and 4. No power. I don't have a wiring diagram for this car. I would love to have a diagram if one is available.

OK, let me explain what happened to get me to this point. I decided I would check the timing. I needed to clean the markings so I was hitting the starter several times to bring the markings around so I could clean them. I hit the starter maybe four times and then it ran like crap. I have no power to the idle speed valve at the front of the engine and none at the control unit under the dash, I think. Any ideas why this happened and where I should look to restore the power? The drawing that was posted shows power coming from fuse 14. It is good.
