Fitting an 04 tach to a 99 FXDS

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
