Below are both rectangle and round variations of the wiring. I was pretty pedantic writing it all down but wouldn't bet my house on it. It did work for me though.

These are the wires from a Round Cluster (clock not tacho) that was taken from a ute being wrecked. I am unsure of the year.

1) Yellow/White (temp gauge)
2) Black (earth)
3) Green/Black (Right Turn)
4) Green/Blue (Illumination Lamps)
5) Green/Red (Left Turn)
6) White/Red (Charge)
7) Yellow/Red (Brake)
8) Green (12V)
9) Yellow (Fuel Gauge)
10) Black (Earth)
11) Red/White (Beam)
12) Yellow/Black (Oil)
