Ok, I didn't take pictures of the whole process because im too lazy however I will give you the basic hint on what to do
Flathead screw driver and pliers or a plug remover
First you need to remove these plugs from the side you want to change the bulb/replace the tail lamp
After you remove those you need to twist off the two plug/holder/god knows what to call them things that hold up the net:
After you remove those, pull the carpet back and there you have to unscrew three plugs that hold the tail lamp on, they are twist off so it's very simple~
And then there you go, Finished.
