Question how to replace rear O2 sensor on 2003 xtracab?

I have a P0136 error code with a readout of bank 1 sensor 2 sensor malfunction. I learned that this is the rear O2 sensor. I found the sensor under my truck, but the wiring runs from the exhaust pipe into a rubber gromet in the floor under the passenger seat. I want to replace the sensor myself but do not know where I should look for the connector. Do I need to remove the passenger seat to find the connector?
Thanks,
Jim.

With sufficient thrust, pigs fly just fine.

Removeing the passenger seat is easy. The you would need to remove the door trim, and you should be able to reach it under the carpet from there. Its an easy thing to do.

Did changing just the rear 02 solve the problem? I have been told this code may also be a faulty cat....
