1985 Monte Carlo SS: ci..wiring diagram for the oil gauge..idiot light

Customer Question

1985 Monte Carlo SS 305 ci. We need a wiring diagram for the oil gauge. we can only find one for the idiot light version. The gauge reads either maximum pressure or zero pressure and we are not sure where to look for the problem. Any help would be appreciated. Thank you.

Does it go to zero if you unplug the sender at the engine?

Now ground the wire, does it read max pressure?

Reply to Hammer Time's Post: There are four wires to the sender, which one would we ground?

Are you sure you have the right sender? It shouldn't have 4 wires.

Reply to Hammer Time's Post: There are four wires going to the plug but only two have pins that connect to the sender. Sorry for the confusion.

Try connecting those 2 together and turn the key on momentarily
