Tips & Tricks
- →You do not need to remove the entire interior panel to disconnect the wiring connectors — use a small screwdriver to unclip them through the opening instead.
- →Be careful not to drop the three 10mm nuts inside the vehicle — they can roll around and cause rattling noise and may be difficult to retrieve.
- →The studs are intentionally long on this vehicle, which helps prevent nuts from sliding off during removal.
- →The top mounting nut is harder to reach — loosen it with a small ratchet and finish by hand.
- →The replacement tail light assembly may not come with bulbs — transfer the bulb sockets from the old unit.
- →When reinstalling the tail light, align the green clip with its slot first, then line up the bolt holes before sliding it in.
- →When reinstalling trim panels, make sure the weather stripping is not caught underneath.
