To operate the existing tachometer these components will be required:
A flywheel with three tabs.
The existing crank position sensor to sense the flywheel tabs.
The ignition control module (EZL).

The EZL signal that drives the tach appears at pin A4 (TD).

So it should work if I already have all of those components?
Even if none of the other pins (camshaft sensor, coils, knock sensor, etc.) are connected to anything on the diesel engine?

Thank you.
