First remove the tail light assemblies from the vehicle. Remove the two plastic wingnuts from inside the trunk, remove the 10mm bolt located to the left or right of the license plate and the tail light assembly should pull out. This is shown in your owners manual page 6-31.

Notice the small center lamp socket, this is what we are going to modify. (shown before any mods) Remove the turn signal assembles from the vehicle by removing the lamp sockets and wire keepers, we want
