    oil pressure gauge

    I put a 5.3 in my 1997 obs

    Im using the factory harness
    Im stumped on why is my oil pressure gauge doesnt work

    I know I have oil pressure because I checked it with a mechanical gauge
    According to the wiring diagram the tan wire is for the oil pressure gauge
    I replaced the sensor
    Also my voltage gauge isnt working

    What am I missing?
