it's is very straight forward.
for the outer part of the light, remove the carpet (there is like a clippy thing... you'll see it) and you'll see a connector (i believe only one). disconnect it, and then there are either 4 or 6 screws. when you get those off just push the light out from the inside... make sure you push the middle.
trunk part is the same way... move the carpet, and then just screws and push out.
