I tried searching but no results that i need. Can anyone show me which wire to hook from the ecu is the o2 censor so i can wire up my a/f gauge?

 

It's the solid white wire coming from the O2. I just run a wire from the bulkhead to that point, as when I use my WB02, I hook the narrowband output on the wire and plug it into the narrowband plug so I can remove if required easily.

If you look for an OBDI pinout, it will show you where on the ECU side to hook it up.
