1992 Nissan Pickup Truck. A long while back (several years) my gas gauge and temp gauge when out and don't move at all. I have to wait for the yellow low fuel light to come on before I fill up. Everything else works, battery, clock, speedometer, idiot lights, odometer.
Now this morning, my speedometer stopped working which controls the odometer (I imagine because that stopped working too). Battery gauge and idiot lights still work.

Where are the relays or fuses for the instrument panel. I've tried looking in the standard fuse box under the dash, but that's not it.
Help
