I did a hatch swap about a year ago.

There are 4 bolts at the top and 2 on the gas shocks, to get to the ones at the top you will need to remove some of your interior panels and the headliner. Those are easy, just pull on stuff till the clips come off. I didn't have to cut off any wires, just follow the wires until you find the location of the clips in the harness. I think they are located behind the panels on the sides of the rear seats. Installation is the reverse of removal. Just remember to put the wiring grommets back into place or an automatic car wash becomes a very interesting experience.
