I got one from ebay for a project and IIRC the wiring diagram on ebay was different to what arrived. Let me dig it out and see what colors go where.
edit: I dug it out and mine are very different to that configuration. In addition, the speedo sensor that goes at the wheel is wired with different colors that the dial side of the plug but it's the only 3 pin, so that one is easy. The wires that go to 5th gear etc are for the gear indicator, and are probably not needed in this case. The two pin plug is 6th gear indicator. That just leaves the 6 pin and 9 pin to work out.
On mine, the six pin plug is for Neutral light plus gears 1-5. 9 pin coming up. Of course there's no reason to believe that mine is the same as yours, but it might help.
I'll be back ...
