Dash Cluster Connector Pin Diagram

I am rewiring my 1966 Skylark with a Painless Wiring kit. For the gauge cluster connector, it says to reference a factory wiring diagram to see where each wire in pinned to the new connector. Does anyone have a wiring diagram for the dash cluster? I just need to know which pins for the dah go in which slow into the 12 pin connector. A search online yielded nothing.
Thanks in advance.

 

This is what I found after an online search:

 

Here's a bigger image of the connector:

Thanks for this - you must be a much better search engine user than me. Interesting that some of the wires Painless is directing me to use seem to go to different connectors on this diagram. I'll have to spend some time looking through in more detail.
Wiring is definitely not my forte so appreciate the assistance here.
