Its the purplish blue wire, you can get a a/f pig tail from Intense, zzp, caspers etc that plugs into the existing o2 sensor for a clean install.

Air Fuel ratio gauge...... to let you know if your running lean or rich.

BTW.... did you make sure you can use it with your car?
I think some A/F gauges say to use only on cars with a 90amp alt or lower.

Why do you even WANT an AF ratio gauge?

Well, usually the AFR gauge is used for cars that have HEAVY mods, and typically have an AFC calibrator also. Knowing what your AFR is won't do you any good since you can't adjust it anyway. Not only that, but your stock PCM keeps it in range.

The gauge may just frustrate you.
