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?

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.
