Reading wiring diagrams seems really hard at first, but like mentioned above, it’s just lines. For more complex diagrams: Print them & get some different color highlighters. Trace each line from connection to connection in a different color. Maybe do some research on how read them. With an older car, these things are good to learn. Also note, only certain lines will have power on them, others will be grounds. Others yet will only show power when the right conditions are met.

My $.02: S-chassis clusters are old & crap out, but they are cheap and easy to replace. If testing each connection from point to point is too daunting, just swap a different cluster in and see what happens. Worse case scenario, the problem will be the same.
