So your saying there are 3 wires.

Black.
Green.

Red goes to ignition power

Black goes to ground

Green goes to ECU for o2 sensor

You can get just as much information from it if you hook the sensor wire into the stereo output.

If you've not installed a wideband O2 sensor, don't bother with an AF gauge.
