Help with gauge cluster pin location on 70 Chevelle SS

Hi all,

Been searching for days to figure out how the wires are supposed to run into the cluster connector on my brother's 70 Chevelle with the gauges. We have looked/bought about a half dozen different wiring diagrams and they don't seem to be complete. Does anyone know where I can find a break down by pin number? I even found a few pictures on line, but the wires seem to be in a different order.

I'm also wondering how the ammeter is wired, is that part of the cluster connector? I have the 2 black wires and 2 empty pins in the connector but that just doesn't seem right.

Any help greatly appreciated!!!!!:banghead:
