    OIL Sensor

    There is a sensor in conjunction with the filter housing. The wires going to it are FUBARED and I want to replace the female connector fresh wiring as the piece is bad also. I cannot located any part of that sensor unit anywhere in OEM. Anyone know how to locate it or the part number or what is its function.

    Are you referring to the oil pressure switch, part #16?

    Yes that's the sensor don't know why I missed it in OEM but I need the plug as the wires are pulled out and brittle. Not sure the male connector would be listed anywhere other than generically.

    Correction that would be the female connector from the wiring harness to the sensor.

    Believe the oil pressure switch requires the standard 2 pin fuel injector plug, although this is only an 1 wire switch.

    Probably the easiest way to swap in the new plug is to cut out the old one. Use a dremel tool or a sharp wire cutter and carefully snip/cut out the old housing taking care not to damage the old connector pin. When done, just insert the pin into new plug. Make sure the connector pin is oriented correctly, otherwise, removing and reinserting the pin again without the proper tool is a major pain. https://m.eeuroparts.com/Parts/53898...or-1287013003/
