    Tachometer wires

    Hi,

    Can anyone tell me what wires give the rpm and speed signals to the tachometer? It would be a lot easier if someone told me instead of measuring all the wires

    If you know what signals I can expect to come out of them, even better!

    Regards,
    Tom

    As Lee says a green wire in pin 20 of the instrument panel connector for the RPM

    If you need speed pulse thats a Red/Blue wire in pin 27
