1986 pontiac gp wiring issue for rally gauges

[Klingerm]

Trying to install rally gauge pack on on 86 GP. Have all working but oil pressure. I have changed sending unit but can't get gauge to work. Wondering what wiring will need to be changed

Not on Pontiacs. Other than getting the right sending units, plug and play.

I just replaced mine... the gauge was dancing on me and sometimes trying to give me a heart attack by registering 0.

I grabbed a STANDARD MOTOR PRODUCTS PS155 from rockauto.. altho Im showing the local joints have them, but a little more costly.

My oil pressure gauge works great now.

As stated above, the sender unit for a gauge is different than the dummy light sender.

See if these help you any. I found them helpful when I wired up my GP dash.
