Speed relay for 911 1969-1975 (and 914-6)

The speed relay is mounted on the rear fuse panel and checks the accelator pedal position and the engine speed. The relay is called into action once the driver lifts his foot from the pedal as the engine is in overrun.

If the engine speed is over 1.500 rpm in overrun the relay cuts off the fuel injection. Once the engine speed falls below 1.300 rpm the fuel injection will start up again to prevent the engine from stalling.
