Aw shit dude this is easy. At least on a Coupe, dunno about sedan. But basically you open the trunk and remove a couple of plastic "bolts" that hold the extra thick carpet stuff in. Once you're done there you can remove the corner tails with like 3 or 4 bolts holding them in. Remember to "twist" the bulbs to get them out and REMEMBER which bulb is which.

The middle piece is a tad bit trickier, It's only held by like 4 bolts, but we thought there was 5 so we kept looking for like 20 minutes making our necks hurt lol. Eventually, we figured out it was just four and used a flathead screwdriver to pry away the gasket holding the middle piece in and them whammo it popped out

WHAMMO
