02 sensors help

I recently did a swap. I put in a 2000 4.0. I had to buy the engine harness and comp separate. My question is most tj s 2000 up have the mini cats w 4 o2 sensors. My harness has 4 connector but one of them is on the passenger side of the engine near the starter area. The other 3 are on the drivers side. I'm not sure what is going on here with this harness or where my sensors should go. Is this a model that does not required the mini cats? Thanks

Mine has four 02 sensors and if I remember correctly the rear down stream rear sensor comes across the top of the bell housing from the passenger side. It has the mini cats also
