Going to add my contribution since I just did this repair. It's pretty easy, you'll just need a T25 bit, a trim tool, and a pick.
1) This step may not be entirely necessary, but it gives you much more room to remove the piano black trim from around the rear vents. Remove the trim directly underneath the arm rest. I found this to be the hardest part since I didn't want to risk breaking tabs. Just go easy with the trim tool and it'll eventually pop off. If you break it, it's part 31377911. After you pull this off, you'll remove the 4 T25 screws, and then the arm rest pops off.
2) Use the trim tool to pry the trim around the rear vents. It's easiest to start from the top and work your way down. The trim is attached to the vents, so it'll al come out together. If you want, you can also remove the 12V panel to give you extra room. I have a 16 T8 hybrid, so I also had to remove the panel below the 12 panel on the tunnel (where the high voltage disconnect (I believe) is). This lets you push from underneath or help line things up if needed. Now is also a great time to clean up the rear touch screen since mine was filthy around the edges.
3) To remove the trim from the vent assembly, carefully pry up on the tabs that go all the way around. There should be 8, 4 on top in a row, two in the middle together between the round vent adjusters and there are two tabs slightly hidden under the round vent opening adjusters at either corner. I used a pick to help with this
Installation is the reverse of install.
Going very carefully, this took all of maybe 15 minutes.
