Ok I have an empty gauge pod and my friend gave a an air/fuel gauge so I'm just going to use it for the hell of it. I have a 92 civic dx with a turbo b16 setup. The gauge has 3: red, black, and grey. Power, ground, 02, correct?

The 02 has 4 wires. I figure one of those is more accurate then the other and that is the one to tap into, correct? Anyone happen to know which one that is? Any install a air/fuel gauge in an eg before?


Holla back.
