Thread: Stock oil pressure sensor, LS harness adapter.

  1. #1

    Default Stock oil pressure sensor, LS harness adapter.

    I have a Dominator setup going in '02 Trans Am. Is there an adapter to go from the Holley harness to the stock sensor? If not, what thread is the stock sensor? I have a Holley stand-alone Digital Dash setup, but the Holley sensor is 1/8 NPT. Thanks, Chris.

    I think the stock '02 sensor is just a single wire, which isn't really a sensor, just a on/off switch. The Gen IV 3 wire sensors are actual sensors and will work with the Holley EFI. I use a ACDelco sender with my Dominator.

    Or you can get an adapter (16 mm to 1/8" NPT) and run the Holley sender. Andrew

    The original 1-wire version is a pull down resistor type of sensor, which isn't compatible with the Holley EFI.
    Definitely buy the adapter and get either a Gen 4 3-wire sensor, or get any 0-100 psi 3-wire sensor.
