Help with gauge cluster pin location on 70 Chevelle SS

[northput21]

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!!!!!
