can someone tell me what wire runs to the oil pressure sensor and where the sensor is located my car is an 84 rx7 gsl with a 12a thank u

 

Sensor if underneath the oil filter pedistal, looks like a brass mushroom. It has one yellow wire with like a plastic snap-on connector. The unit (I'm guessing) grounds itself to the block, because it only has 1 wire.

Here is one on a few adapters. Idk why it'son adapters here, but Google search found this for me:



The nub on the tip of the thing is where the wire clips on.
