Air/Fuel Ratio Gauge
Was wondering if anyone knew which wire on the o2 sensor i connect to the air/fuel ratio gauge. The wire is located right behind the air intake manifold. Its a grey connector with four wires.

You can't hook up a normal "A/F" guage on this car. It uses a WBo2 sensor that outputs current insted of voltage. I supposed you could hook it up to the post CAT narrowband.....but what good is that
You should put in a stand alone WBO2 that will give you values that mean something

However, the info you gather from the rear O2S is useless, unless you are just concerned with your emissions efficiency.
