If memory serves me correctly you need to fit a wide-band sensor separate from the car's original one.

I know on the 4.3 system the original sensor is narrow band and also grounded via the ECU.

I'm sure someone will correct me if I'm wrong.

Also is there not some calibration resistor fitted into the plug i think ??
