Where are the 02 sensors???!!!???

I have a bad o2 sensor in bank 1 position 2. I have tried to find any info online but seem to be looking for a needle in a haystack. I have a 2003 Jeep TJ with the 4.0 engine. Does anybody have any pics or an idea of which sensors are which? Thanks in advance!!!

It would be behind the cat if you only have 2 o2 sensors

If you have 4 o2 sensors it will be on the front 3 cylinders pipe behind the cat
