temp. gauge
How about Oil pressure?
The Instrument cluster voltage regulator runs these systems.
To check the gauges with the key off:
Take the connector for the oil pressure sending unit off
put a cotter pin it, now attach it to a good ground,go back and turn the key to ON > If the gauge pins to the high side the gauge is good.
Now do the same with the temp sending unit.
Location of the S/U ,Depends on which engine you have.
If the gauge DOESN'T pin, there is either something wrong with the gauge,wiring,or IC V reg.
To check the IC V.Reg with key ON:
Take a test light and attach it to the sending units wiring.
You should have a PULSING light.
If so, the IC V. reg is Okay.
If Not,either the wiring is bad or the V reg. is bad.
The IC V.reg is located on the back of the instrument cluster.
So,If you have a gauge that Pins and a Connector that Pulse flashes : the problem is with the sending unit.
Check the S.U. for teflon tape wrapped around the threads.
If so,remove it and check it again for gauge reading.
Always use the proper sealant for sending unit threads.
Teflon tape is insulator
You need a conductor sealant.
Oil pressure change :
Usually from a worn oil pump or from the expansion of the cam & crank bearings causing the pressure to lesson when heated up.

temp. gauge
Depends on what engine you have. On a 302/351w/460 it is threaded into the intake manifold. It should have a red wire going to it that has a angled boot the just pushes on it.
On a 351m/400, it is next to the waterpump in the front of the block.
