Downstream O2 sensor on '06 AWD

[mongoose70]

Ok, I've searched endlessly here, to no avail, so this is my first post. Replacing the downstream O2 sensor, wiring comes through passenger floorboard underneath seat, then to where? There seems to be a myriad of wiring harnesses that plug in under the seat there but cant locate the right one. I've seen the YouTube vid where they replace this on an '05 FWD, but the wiring shown in that video looks NOTHING like my car (I assume its an AWD thing). And of course, the Haynes manual is of no help in this matter at all. Any help, ideas, insight etc would be greatly appreciated. Thanks!

Do you think you could get someone to tug on the wires under the car while you look which ones move inside the car?

just a thought.

AWD has many things that are just a bit different. Does your car have the monsoon audio package? The connector for the FWD and the AWD O2 sensor is the same, just slightly different harness location. Not sure which thread you checked, this image of the connector in this video may help get narrow down which wires in the harness go to the O2 sensor

The list parts number will also be slightly different due to the length of the wires coming off the 02 Sensor a quick search returned the following:
