Default Looking for O2 sensor signal - stock ECU
I'm looking for the front O2 signal pin to wire in a UEGO to my stock ECU, but I can't seem to find it anywhere on that pinout sheet. I see the front and rear O2 heater control pins on 3J and 3P...is that the signal line? Or am I just missing something?

Thanks!
