don't be so harsh, and actually the cheasy little A/F monitors folks put in their cars are too narrow of a band to do MUCH good, it bounces around like no tomorrow, to tune your A/F ratio you need a wideband lamda meter. A/F meter's are mostly for looks or to tell you "oops to late". It's just another cool gadget to have around, you'd be better off with a simple volt meter tapped onto the o2 sensor, it would give more accurate readings but would still bounce all over the place. To truely get a picture of your fuel delivery, you need to first have it tuned with a lamda meter and have your fuel curve mapped, then by using an EGT meter and an A/F meter you can "kind of" tell how it's running.

Here if you want to be a bit more accurate
http://www.2gnt.com/www/corbin/dvm2.html . If you figure even the best A/F meters only have 20-25 digit resolution(meaning there are only 20-25 lamps on the meter) with a voltmeter hanging off of the o2 sensor, you have the same resolution as the meter does.

also for the original post, it's pretty easy to find your O2 meter, just start from your headers and go back until you find a little thing sticking out of the side of the pipe with either 1 or 4 wires(possibly 3 if it's grounding through the chassis) on it depending if your O2 has preheat or not.
