JMDUNN:

I checked 4 different WEB parts providers including this sites Parts Shop and Fastlane. All show a "reference sensor" located at front crank pulley - sounds like a TDC sensor. The optional part number shown is 001 158 91 28.

All sites listed this part as being unavailable. Sounds like a dealer item.

That sensor is ONLY for info to the factory scope(when connected). HAS nothing to do with the running of the car.

thanks a lot M.B. Doc. , COuld you explain to me how the ignition control module works. This is my first non point type ignition.

The distributor creates an increasing A/C current signal to the EZL.
