It should be either the white or the grey. Take a volt meter and put one lead to ground. Then take the other and push it into the wires(with the car running) until you find the one that cycles.

I have an autometer A/F guage. I hope you don't plan to do any tuning with it... worthless. All it tells you is if your in open or closed loop.

Thanks for the info. Ok so the A/F gauge can not be for tuning? just for show you think if I plan on tuning I need one that is the volt meter kind? Thanks for you time D L L

If you want to know your true A/F ratio you need a wideband 02 sensor.

The pocketlogger is definitely the most useful tuning tool.

An EGT guage is also somewhat helpful. Not as useful as a wideband or a logger, but definitely better than a narrowband A/F guage aka. blinky light show.
