Jeep 3.6l O2 sensor location/diagram

Hello all,
Wanted to know if anyone has a diagram of the 4 O2 sensors locations on the Jeep JKU 3.6L engine? Or could shoot a link to a previous post or website? A lot on YouTube shows all Bank 1 sensors 1/2, no Bank 2 sensor 1/2. Appreciate the help.
Cheers.

Not fully understanding the question, but here is what info I can offer: The cats on the 3.6 are pretty much right off the heads (1 per side instead of having 1 large one after the ypipe). The O2 sensors are directly before and after the cats on both sides. It shouldn't be too hard to locate them. If you are replacing them, do it one at a time. It can be easy to mix up the plugs.

From the maintenance manual:

Left (driver) side catalytic converter; #2 is the upper O2 sensor.

Right (passenger) side catalytic converter;#1 is the upper O2 sensor, #3 the lower O2 sensor.

You'll want to use an O2 sensor tool like:

Thanks for all the input. I assume the easiest way to get to Bank 2 sensor #2(downstream) is to remove the wheel liner on drivers side first. Then it looks like I should be able to see both Bank 2 sensors #1/2 near the Cat.! I plan on getting the loaner tool for Autozone to help remove the O2 sensor(PB blaster and some heat too). Thanks again, just need to know the location better.

Yes, for the driver side it's recommended to remove the wheel liner.

For the passenger side it's accordingly a b**** and you may have to remove the battery tray which in itself is a major PIA.

Was looking for this information as well. Note that the o2 sensor tool is something that autozone loans out for free
