I've been trying to swap a 9C1 cluster into my 91 wagon for a little while now, but I've gotten stuck on rewiring the car to the 9c1 connectors. I'm hardwireing them in, but I'm having trouble with connecting the proper wires together. The only 9C1 connector pinouts I've found are too blurry to read. Most writeups seem to be for RM clusters, which apparently have a different pinout (thanks GM!🙄).

I've gotten pretty far relying on colors, but some colors are reused, so that's stopped me. Any wisdom on this is greatly appreciated, thanks!
