The brake light cover just pops off, but it has some reverse hooks that take some massaging to release from the carpet. The brake light housing then lifts up, as I recall, with spring clips pointed down. Pop off the c-pillar covers, swing down the rear seat side bolsters which I think just unsnap from the top, remove a handful of push fasteners you see missing from above, maybe peel down some trunk liner too. Look around, if the carpet is still under another part, look to see how to remove/move that part first
