Hello I have a 94 Chevy and I have an issue that seems common but I have not been able to fix. My gauge lights do not work. I tested the switch plugged into the harness and the dimmer works the headlight switch works outside lights all light up and gauges operate correctly. I checked what I thought was the right wire from the dimmer switch (green) to what I think is the same Color on the plug (green) and no power there so I assume break in the wire? May try and re use both connectors and put a new wire in line unless it could be something else

Wiring diagrams would be in the GM manual. You can download PDFs of the here. If the earlier manuals are like the later years, there is probably a diagnostic table in there somewhere for troubleshooting inoperative cluster lights (if your bulbs are good).
