    Oil Pressure Sensor on top of the engine on the Drivers Side

    Hi everyone. I am almost done with the LS Swap on my 97 2 door.

    On the back of the engine up top on the drivers side, there is what I am guessing is the oil pressure sensor. The plug on the 97 has 3 wires...




    The plug on the LS engine only has one wire...



    The harness will be wired differently depending on what sensor is used.

    I'm not using the computer from the 97. Only the computer from the 02.

    Do I need to use the old sensor so the gauge on the dash reads correct?
