AIR/FUEL-Ratio gauge fitting????????
 

Does anyone know how to fit one iv got one and it says in the instuctions to connect the wire from the gauge to the feed wire from the o2 sensor that goees to the pcm? there are three wires from the o2 sensor two white and one black and they all read the same voltage:confused: any help will be nice

You need to connect to the black signal wire, the white wires are the heater.
