To all,

I know the o2 sensor is somewhere behind the engine, but does anyone know where. I haven't looked yet, but I got a a/f guage/switch for my nitrous setup and I need to tap the a/f signal wire from the O2 sensor. I'd rather have some help and know where it is before I start. Let me know. Also, if you know what the color is of the wire that I need to tap, it would be helpful.


Thanks.

Take off the engine cover and you can see the 2 sensors on each side. i would tap into the one/ones before the cat. remember you have 4 sensors, 2 on each side.
This was a concern of mine at one time, if you tap into one side and the other is lean you'd never know. So you would have to run 2 sensors, one per side. I would prefer to use Wide Band AFR gauges and sensors, not sure if our O2s are wideband.
Sorry don't remember the colours for each side.

Andrew, We Miss and Love You!
