That green wire is the shielded cable. The black wire on the sensor is a
plain wire.

I had a really good look at the wire sheath, and it does not look like
coaxil cable at all, simply a rubber cover. The wire coming out of the
o2 to the quick connectors is actually black, not green... although it
looks like it connects to a green. Is there another type of o2 sensor
that doesn't use coaxil cable?

to the center wire. The two white wires are for the heater in the
sensor. Make sure there is 12 volts when the engine is running. The
sensor should also have shield plate to keep air and road debris away
from it.
