as the title says, i am trying to hook up an air fuel ratio guage and i would rather hook it up at the computer then the sensor it self, so does anyone know what wire is the ref wire for the o2 sensor at the computer? Or a diagram that shows what wire to hook that guage to?

I did a search, it seems to be the white wire in the first clip (the D clip) can anyone give me an actual pin number?

ahhhh, nothing like finding your own answer http://www.92lude.com has a pin out chart for the prelude

Pin d-14 is the heater o2 sensor signal (white wire) on a p13/14 obd1 ECU for all those that ever search for the same question

 

its the thicker than all white wire, we've gone over this a million times, try a lil search action
