I recently got a set of gauges to install. I have all of them installed and working except for the A/F gauge. It shows that I need to connect it to the signal sending wire of the O2 sensor. I have searched the net, I have searched here and I can not find anything that says which of the 4 wires is the correct one. Anyone know or know where I can find out this info?

thanks.

 

On my lunch break ill check out mitchell on demand. Usually i can find a good wiing diagram through them. Or you can call infiniti ask for the parts dept. and ask if they can send you a wiring diagram for the O2.

 

Hope that helps these dont seem too specific but they are from infiniti.
