Default Need help installing Air/Fuel ratio gauge on S4.

I was wondering if any of you have an Air/Fuel ratio gauge in your S4. I just wanted to ask you you know what wirs is the signal wire from O2 sensor and also which sensor should I hook up to....rear one's or front one's. Any info will be greatly appreciated......

Default The stock sensors are narrowband so an air/fuel gauge on them is pretty useless.

Just flashing lights. If you really want to know your air/fuel ratio you need to install a wideband sensor and gauge such as the Innovate Motorsports kit or the AEM kit.

Not exactly. They are useless for tuning, but are still a good indicator if something is wrong.
