Step 2: Remove the 2 mounting plugs that hold the plastic trunk panel in place. Remove the panel, exposing the mounting area.
Step 3: Remove the three 10mm mounting nuts that hold the tail light to the vehicle.
Step 4: You can now remove the tail light assembly.
Step 5: Disconnect the wiring harnesses from the back of the tail light 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, simply twist the sockets counter-clockwise, remove them from the old assembly, and attach them to the new one. This process only takes a few moments!
Step 6: Connect the wiring harness to the new tail light assembly.
Step 7: Mount the tail light by tightening the 10mm bolts to the assembly's mounting studs.
Step 8: Cover the area with the plastic panel and secure it with the mounting plugs.
