    What are y'all using to keep the factory temp gauge in a 94?
    This truck has a Nelson harness truck temp sensor
    The oem 350 had a one wire sensor

    i'm using this in my 96 on the factory gauge. it's a 3 pin sensor with a mini harness. the third wire goes to the factory gauge. i heard a few guys say they aren't accurate but mine is & i've had no problems.



    i bought this off ebay all together. i think the sensor is from an older camaro, & they do sell the harness separate.
