The wiring is the easy bit, you need the fuel flow sensor for the MKi setup (which bolts on the side of the metering head).
You may be lucky and yours may already have it, or you may be able to pick it up from the fuel ECU, but am not sure on that TBH.
If it was a late EFI-one, you would just go straight to the main ECU for the connections.
Connections (if you get that far though) should be:
1/ Red - +12V
2/ Grey/Green - illumination
3/ Brown/Red - fuel tank sender (separate wire to the fuel gauge where it goes onto the tank)
4/ not used
5/ Brown - Earth
6/ Brown/White - Speed sensor (on gearbox underneath speedo cable)
7/ Brown/Green - Fuel flow sensor
8/ Brown - Earth (connected if MFi, disconnected if EFi)
9/ Black/Yellow - ignition +12V feed
On EFi models
Same as MFi, except pin 7 goes to pin 17 on the ECU
This is all going from memory though
