Default Trailing Cable Under Car

Good morning,

I've discovered an abused cable hanging under the mid-driver side undercarriage. It appears to be a downstream O2 sensor that fell out of its socket and has been rubbed down to a nub but it could well not be. Would anyone give me a step by step on pulling this wire and replacing it?

The post cat O2 connector harness is under the front carpet. You'll have to pull that up when replacing the sensor.

This thread has some tips and a video link:

Just to note that a pin head sized dab of the copper based anti-seize is only necessary.
