[QUOTE=cobalt $$;132241]I was wanting to know how to hook up a air fuel gauge on the stock cobalt ss/sc o2sensor! If anyone knows what wire please let me know thanks. The 02 sensor has 4 wires I need the signal wire color.

signal wire should be purple or blue

speakin of air/fuel gauges, how do you hook one up on an LS? same wires?

signal wire should be purple or blue

On the sensor itself it has (2) white wires a black and grey.
Or are you talking about the harness from the car that plugs to it, it has a blueish green color wire is that it?
