I've looked into this a good bit at this point. I'm going to get a service
manual, it should have the page I need like stated below.

I've looked at everything I can get my hand on, including the schematics of
Bosch sensors and have seen nothing mentioned about air. Not sure what
that even means myself :-)

Thanks for the info!

He's right about the air charge. Not sure of the exact usage, and
couldn't find it in the service manual(note time of post<g>), but the
wires to the sensor *do* indeed carry oxygen to the sensor.
At GM electronics training classes we were told *not* to splice the O2
sensor wires, just for this reason.
I've heard of cases where a really bad running engine, which is
dumping a lot of oil into the exhaust will wick the oil up through the
harness into the PCM.

Re: 95 Wrangler O2 Sensor Wiring HELP!
 

Some have the air charge coming in around the case to wires joint and
some have it coming in along the insulation for one wire.

This is the outside air charge needed to compare to the inside to make
the signal if any.

I asked 'mic canic' which wire because I for one don't really think he
knows which O2 sensor goes where or which is which.

One type has to be crimped to 'jury rig' it to fit and the other type
can be properly soldered and heat shrinked to jury rig it.

The best is still the one that fits properly......

I've heard the same story about O2 sensors and one I replaced in a
Mitsubishi PU several years back came with very detailed instructions
on how to coil any excess leads, don't pinch or kink the lead, why you
couldn't cut the lead off, etc. Same for an old Buick - but these
were the old single wire type of 15-20 years ago so I'm not sure how
they apply to current sensors. They've made at least some progress in
the last 15 years.
