Help, cant find something.

I've been having trouble with wiring my O2 sensor from the bottom of the car.theres a hole coming up through the car, but I cant find where that hole is inside the car. I ripped up the floor around the upper console but I don't see anything. I've been writing this post in the technical section but I want to see if you guys know because you have the same car. This is the secondary o2 near the cat converter.
