How do you change the tail light on a 2004 Mazda 3?

Answer to install tail lts. Mazda 3wow...it's a lot of work! First of all be careful to hold on to all your parts! When we were installing the taillight on the trunk lid a small plastic piece fell in and we had to fashion a little grabber to get it out. to get the large piece of the tail light out you have to unclip all the clips to get part of the carpet undone and then have to pop out the whole black plastic piece that does over the latch. after that it's just a matter of connecting things wherever they need to go. putting in the old taillights and connecting wires and stuff. It took us like 2.5 hours to do this, but if i knew that i was doing it probably would have taken an hour...and if we didn't drop that plastic piece. Good luck!
