I just got done with mine. There is really no particular order in which to install the pieces. This is the way I did mine: Install back seat cover piece, sides of trunk and then the floor. I did the tail light piece last, and is has to be glued in place. There are some small pieces that also need to be glued around the trunk hinges. The reason I did the floor last is because that piece of carpet is not near as large as the factory piece and you need to custom fit it so it covers the floor. The kit overall is ok. BUT.. it does not come with any material to cover the spare tire area like the factory piece did. I just went out and bought some matching carpet to do the spare tire area.
