P0161 Code on 97 F150 4.6L 4x4

I downloaded this code--O2 Heater Circuit Bank 2, Sensor 2. Can anyone tell me where sensor two is? I saw an orange sensor in the exhaust pipe that looks like it could be it, but don't know how to be sure or how to know if this is sensor two and not sensor one.

Thanks in advance.

P0161 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2) - Passenger side after the Cat. Look for damaged wiring, corrosion/water in the wiring connector. Good luck.

as Driver side in the middle of the rear cat.
The sensor is heated from a 12 volt supply through the harness as well as sends an Oxygen monitor signal on a separate lead to the computer for the health of the cats on that bank.
This checks the ratio of switching between the front and the rear as the way it does monitoring.
The Heater circuit function is in fault.
Good luck.
