you can run it off the o2 sensor purple wire all day long. Iv done that on 2 cars and never had an issue. Or you can get it from the PCM wire, which is still the purple wire just alot closer to the PCM. I thougt there was a way to get it from the port but I wouldnt do that. Just use a good connections and get it from the o2 sensor. And power from the dash fuse panel.

Won't do you much good to wire it into the stock O2 sensors since they response band is only about 14~15 AFR. Get a wideband.

mine works fine,,sure,,its not super duper accurate due to being a single band,,but i also dont have 200 to 400 bux to spend on 1 guage either....

you can tap the Purple wire that is in your wire loom that runs along your drivers side fuel rail.
