Step 1: Loosen and remove the T15 Torx screw located just above the exterior tail light's lens.
Step 2: You can now remove the tail light assembly.
Step 3: Disconnect the wiring harnesses from the back of the assembly.
NOTE: If you ordered your replacement tail light from Go-Parts, it likely includes new bulbs, as most of our models do. This saves you an installation step! However, if your particular model does not include new bulbs, simply twist the sockets counter-clockwise, remove them from the old assembly, and attach them to the new one. This process takes just a few moments!
Step 4: Connect the wiring harnesses to the new tail light assembly.
Step 5: Mount the tail light by tightening the T15 Torx screw.
