    Hi folks,
    a customer has just brought in his 99 dyna superglide (which didn't have a tach as standard) along with a tach from an 04 dyna which he wants fitting.

    I know which pin on the main harness is the tach signal (pink wire in terminal 7) but the wiring diagram I saw for the 04 tacho doesn't indicate a signal pin.

    In theory I should be able to pair off the power and ground wires with those on the speedo and just insert a wire into the pin 7 location and ignore the other wires.
    The tacho has a 12 way plug with the following wires described clockwise looking from the front of the connector with the locating tab on the bottom starting with the top left pin:
    orange/white
    brown/white
    green/violet
    blank
    light green/violet
    orange
    black
    orange/brown
    blank
    blank
    blank
    blank

    The harness end has 2 deutch connectors as follows:
    6 way connector:
    Pin 1 orange/white
    Pin 2 brown/white
    Pin 3 orange
    Pin 4 light green/violet
    Pin 5 dark green/violet
    Pin 6 black

    2 way connector:
    pin 1 blank
    pin 2 orange/brown

    Having read up as much as humanly possible online as well as searching through all my HD Manuals I cannot for the life of me figure out which wire actually does what i.e. all I need to do is identift power, ground and signal.

    Can anyone help?

    Thanks
