    Wiring Diagram

    Does anyone have a wiring diagram for the D50 that has the diesel wiring? can only seem to find diagrams with the gas motors.
    Having issues with my tach not working, need to know where it hooks up on a diesel

    I think it is hooked up from the injector pump and there's a signal converter that sends a pulse to the tach. I found a project wiring diagram but not the factory manual schematic...

    If it is anything like a 4d56 in the delica, there is a white wire from the pump that goes directly through harness to cluster, the signal converter is in the tach itself

    thanks for the replies. looks like a white wire coming from the injection pump into the harness, looks like it's time to tear open the dash.

    I got a working diesel cluster. The needle is broke for the tach but you could use it for parts if necessary.
