2007 Tahoe O2 Sensor Issue

[Roadracer6]

OK so I'm trying to figure this one out. Got a code for bad o2 sensor and looked under the Tahoe and noticed the 4 wires hanging down for downstream sensor on drivers side. Went to inspect it and the connector is completely missing. This may have been this way for a while. We purchased this used and there has always been electrical issues. I had ordered 4 new o2 sensors and was about to install them. I did find 4 wires that appear to be cut. I'm wondering if something chewed them off or if they got clipped by the shaft and got ripped off. Here are some photos.....can anybody tell me if these 4 go to the sensor and if so, how do i get a new connector in there or maybe what type and how the wires go.
Thanks a ton! This is a 5.3. The cut wires appear to be pink/purple/gray/brown.

Are all of your o2 sensor connectors like this, or just this one? Which connector is this one (from the photos it looks like drivers side after cat)? If so, then yes those wires do go to that sensor. Here’s the one from my Denali.
I know that RockAuto sells the wiring harness/mating connectors as well as the sensors. I’m not sure if your p/n is the same as mine, so double check that before purchasing.

The removal/damage could have been a “repair” by the previous owner, or could have been an oops from something as dumb as running over a big limb in the road. I’ve seen sticks rip a wheel speed sensors wires from its harness, so anything is possible.
