    Are they still produced, or is a used one my only option?? I called Porsche Norway but they could not find it.

    Info from Zithlord probably from this forum:
    PN 2k 9711 0336611006 "RPM transducer" AKA "speed switch"

    The RPM Transducer receives 12V (ignition-switched) power. When the distributor/tachometer wire signal says the engine is above 1500 RPM or so, it sends power to the microswitch. When the throttle arm contacts (closes) the microswitch when you are off the accelerator pedal, the fuel shutoff solenoid is activated. This pushes the injection pump main rack past full lean and shuts off fuel flow. The engine then slows in RPM. At the point that the distributor says the engine is below 1500 RPM, it opens the circuit to the microswitch and the solenoid retracts, allowing idle fuel flow to keep the engine from stalling.
    I have a small number of these NOS Bosch RPM Transducers 0 336 611 001 offered on ebay. Interested? djtomlinson@hotmail.com
