Hey on a 92-95 civic HB Si (d16z6) a friend of mine is trying to hook up an autometer air/fuel gauge and he wants to know which wire is the sensor wire. He said there is like 4 wires, he just need to know which one to hook the air/fuel sensor wire. If any one knows which wire, I would appreciate it alot. Thanks

your stock O2 sensor is NOT a good A/F sensor! All tt really tells ya if your over 14.7:1 or less than 14.7:1. What ya need is a wide band O2 sensor.
