Need some help, I pulled out my old 88 STD cluster and popped in my new 90 cluster. Couple of problems, one I don't have the original harness from the 90 cluster so I don;t know the wiring order. Two only thing that works in its current condition is the speedometer and fuel gauge.

I did a search and all I came up with was someone asking for help and not getting any. Does anyone have a guide or anything that could help me out?
