Well, to get to your ignition switch you have to take off the cover that goes around the ignition. You can do so with a Philips head screw driver, its pretty self explanatory.

Secondly, i hate to have to be the one who tells you this, but those things are useless. You bought a narrow band A/F gage, all those things do is give your cabin a light show. Basically, the stock o2 sensor in your car has one function, that is, telling your ECU when your car is at 14.7 A/F. Higher than that, it will read lean. Lower than that, it will read rich. Its completely useless for tuning anything. I would sell it, and save the money for a wideband O2 sensor if i were you, its really not even worth the hassle of installing it.

Check out Zeitronix, i chose it becuase it hooks up to a laptop so you can datalog without anything extra. Much faster sampling rate than the LM1 or the PLX. Those are two others you can check.
