Hello,

Hopefully someone will be able to help me. I have a 1982 Ford Mustang. Yesterday, the oil pressure gauge and the temperature constantly read high. We put in a new Instrument Cluster Voltage Regulator, oil pressure switch and temperature sending unit.

Now the gauges are reading constantly low.

Any guidance on what could be causing this problem? Are there wires or cables that are connected to the gauges that could be causing this problem?

We are at our wits end.

Thanks,
Skipper
