Default WHAT WIRE FOR a/f Gauge?

What 02 sensor and what color wire on the 02 sensor should I splice into to get my a/f gauge working on my 06 Corvette ls2.
Any help would be tremendous.
Thanks!

If I understand your question correctly, it sounds like you bought a wideband gauge and are trying to hook it up to one of your 4 existing narrowband sensors. If that's the case, it won't work that way.

You have to put a wideband sensor BEFORE the cats to hook up to the gauge. I use the LC-1. (in Borat voice) "It's very nice!"

If it is an Autometer "Wideband", you need to step up to a wideband O2 sensor and install it in addition to your stock sensors.

It is just a standard a/f gauge, not wideband.

Dude - putting a gauge on a narrowband sensor is totally useless. What are you trying to accomplish?

Guys I appreciate the suggestions, but this car already has the gauge and I just would like to know what wire to hook it up too. Thanks

Please take the gauge out and give specs on it. Make/model that sort of thing. I find it hard to believe that the gauge is meant to be hooked up to existing narrowband sensors. I bet the previous owner took the wideband sensor out and left you with the gauge.

What we are all trying to say is that it a narrowband sensor only reads 14.6-14.8 is not useful for anything other than tuning for fuel mileage. People that try to tune WOT with nb end up with busted motors.
