Default A/F Ratio Gauge Install..

Installing a Air to Fuel gauge, I know it's narrowband and won't show anything, but which wire do I connect to? I've read that it is the purple wire off of the O2 sensor, but I tried that and it just stayed all the way rich..Any help? 2001 Trans Am

Looks like purple is only the high feed to the PCM. Not sure if it will work that way. You may need a WB.

Thanks for the reply..I saw the same on the wiring layout..I tried to hook it up to the purple only and noticed it was stuck on rich, which explains a lot, I guess once I do a cam swap I'll invest in a W/B then. lol
