trying to hook up a air/fuel gauge on a 92 civic hatch and was needing to know which wire is the positive O2 wire?

 

not sure what motor u have but i just conected mine to the car 's computer .spliced the wire.

 

The white wire from the o2 sensor is the signal wire.

 

I have the 1.5 sohc non vtec

 

I have a gsr swap .I got the info from team integra .I sure the is a wiring section on this site so you can see what wire it is for you.I tapped the power from my radio so when the car is on so is the gauge.I just have the light show gauge ,got it from a friend for free .
