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 Guns
