Some gauges not working

So I did a search and didn’t find exactly what I’m looking for. The tach, fuel and voltmeter gauge aren’t working, tack stays at 3500 all the time. Is there a spot where these tie in together? It’s an 84 Z28. Thanks

Re: Some gauges not working

The individual gauges plug into the carrier. The carrier plugs into the instrument panel.

1. Do the Brake and SES lights work? No? Check the Gauge fuse.

2. If the Brake and SES lights work (and assuming no one has done a hack job someplace), you likely have an issue with the printed circuit that's attached to the back of the carrier or where the printed circuit plugs into the instrument panel.

There are two places where the panel plugs into the instrument panel:

I was hoping it was somewhere else but I’ll check those tomorrow. Thanks
