Anyone have an O2 sensor gauge installed? Which sensor and which wire did you tap into? Or did you have a new bung welded in and add a completely separate sensor?

For those who aren't familiar, this is the gauge I'm referring to:

LOL, tell me about it.

I bought the autometer a-pillar gauge pod. I think I'll put an aeroforce gauge in one slot and a voltmeter in the other. I completely forgot that the aeroforce reads all the system settings via the OBD2 port!

I don't know if it's possible on the JK but on my Mustang I just removed a rear O2 sensor and replaced it with the wide band. Then I disabled the rear O2 sensors since the engine management only uses the upstream for feedback. The rears are only there to verify that the cats are working.
