Suggested Repair

Locate the oil pressure sensor about halfway up the engine block, typically under the intake manifold, and connect the unused plug there. Use a mirror and flashlight to find the port; it is not on the oil pan.

Conversation Summary

After an engine swap in a 1994 Chevy S10, the owner cannot find where one plug connects and suspects it is the oil sensor because the oil pressure gauge immediately jumps past 180, though the engine runs and sounds fine. No fitting was found on the oil pan. The expert says the sensor is normally about halfway up the block, usually under the intake, and is easiest to locate with a mirror and flashlight.
