Removing Taillights (Sedan)

[.Kevin.]

fucked up.

Removed the pin closer to the trunk with three tripods no idea how to put it back in it isn't like the others that just push in.

I also opened it and managed to get the two steel nuts unscrewed the light was then severely loosened, I also took off the one bulb then I couldnt figure out/manage to push out that one god damn white pin at the top area, or do I pull it out? I placed everything back out of fear lol

edit: What two studs? I unscrewed to little nuts and thats it
