Re: Name that Wire!!!!! (A3jetta2.0T)

I think that my A/F gauge is hooked up to the wire by itself. That would be the white one for you all though mine is green. Not sure why people put those A/F gauges in. They are just a lite show. You cannot depend on them for accurate readings. I have one and now wonder why I do. I use an LM-1 wide band for A/F readings.
