The tachs on 300D turbodiesels used a sensor reading off the front crank balancer till 1985. In 1985 the read the engine speed off the flywheel.

The sensor on the front of the motor sent the signal to a transducer that converted the induced AC signal into a squarewave pulse that the tach would accept.
