Really simple to take seats out- 2 bolts in the front and 2 in the rear. Move seat all the way back, pull the two front ones, then move it all the way forward and pull the back ones. Gives you a lot more room
May want to think about spraying some penetrating lubricant on the exposed parts of the bolts underneath your jeep. You'll see them if you get down there and look. After my bolts where out, instead of trying to mess with the wiring connector underneath the seat, I just rock the whole seat back and lean it against the rear seat (with seats folded down is best in my opinion to facilitate pulling seat out). Then you can get underneath it to easily pull the connectors. There's a red tab you have to push over and then just pull em apart. I find it easier to (with a blanket down to save your carpet) push seat up onto the back seats (folded down) and pull it out the liftgate rather than try to not mess up your door panels, etc by pulling it out the doors. Good luck.
