I was lookin into buying an Autometer A/F ratio gauge and was wondering how it is installed, does it tap into the o2 sensor signal?

Yes if it is a narow band gauge it taps the o2 signal. There are very good instructions included with the gauge but if I remeber correctly you need to tap the purple wire. If i am wrong i am sure someone will correct me.

yeah its an autometer ultralite gauge and reads narrow band only. so i just splice into the o2 wire and thats it? does it need a ground or 12 volt source?
