Thread: Holley Commander 950 WBO2 controller pin-out?

  1. #1

    Default Holley Commander 950 WBO2 controller pin-out?

    After several weeks of trying to trace a problem I have realized the my wideband O2 sensor has gone bad. I have a brand new five pin Ford wideband O2 sensor, so I would like to use that if possible as nobody over here in the UK has the correct Holley sensor. I have worked out the heater wires, but I can not work out what the pin layout is on the Holley connector. Does anybody know what the eight pins do so I can use this sensor please? Thanks.

    As I recall, the Commander 950 did not use a wideband O2 sensor. It was a basic narrowband sensor. Andrew

    No, the wideband O2 sensor was an option with the later software/firmware.

    Right, but didn't this require an external wideband controller box? I guess it's unclear what the OP is actually working with. Andrew

    Yes, it requires a WBO2 Kit (sensor & controller).
