Printed circuit connector

I am looking for a diagram actually listing the connector use for each pin of each one.

what does each pin provide for? I have the complete diagram but it seems almost impossible to correctly identify what each pin provides power for.
I have built a custom cluster and now need to build a new plug for the cluster.
I have the car apart for now so no I can't meter the plugs.
Thanks to all.
Update: I sat down with the diagram and need to know if you all agree with my findings:
Pin Use
1 12 Volt feed
2 Fuel
3 Temp
4 Instrument lamps
5 High Beam Ind.
6 Left Signal
7 Right Signal
10 Emer./ Low Brake
11 Oil Pressure

Hopefully I have this all right. I am sure someone here will corract me if wrong! Thanks
