1st oxygen sensor wiring to computer

Just curious if anyone has had a chance to follow the wiring from the oxygen sensor into the car? Looking for the feed wire to put in my air/fuel meter.

Find an ECM diagram and tap in there. However, an A/F gauge on a stock narrowband o2 is nearly useless.

I remember the days of a narrowband A/F gauge... lol Hell I remember trying to TUNE off a narrowband... OIE.

Yup, same here. It was marginally helpful in the Camaro to at least let me know if flat spots were lean or rich...but with EFI the BLM value is going to do a lot more with that stock o2 than a gauge.
