Only thing I could think of is the plug in the back of the instrument cluster or a ground wire somewhere. A little more info would be useeful like do turn signals work lights on dash etc.

The Instrument Voltage Regulator (IVR) mounted on the upper rear of the cluster supplies regulated voltage to the oil pressure, temperature and fuel gauges. If it fails, those three gauges do not operate properly. The ammeter is not affected but you can hardly see it move under normal conditions. Tachometer and speedometer are not connected to the IVR. Check to see if the instrument panel lights are working. If not, then suspect a bad ground connection at the printed wiring connector which will affect gauge operation, too.
