Air/Fuel Gauge

Is it still best to just run these right to the o2? Passenger,driver side? Or can you tap into the PCM somewhere?

With the Autometer gauge I had it worked great spliced into the PCM. But when I tried to do that with the Dynotune O2 meter it always read atleast .1mv low so it needed to be connected to the O2 sensor. If you want to splice you can splice PIN #69 on the blue connector at the PCM for bank 1 or PIN #66 for bank 2. #69 is a purple wire with a white stripe and #66 is just purple if I remember correctly.

I will be running autometer. Is either bank better? I was even thinking of getting 2 and monitoring each bank possibly. But for one..does it matter?

It really doesn't matter asuming both banks are running the same. Some people wire up toggle switches so they can switch between the two banks with one gauge.
