Function And Fitment

The holder secures rear light bulbs in their sockets and provides the conductive contact between bulb and vehicle wiring. It is fitted into the right-hand rear lamp cluster, located behind the passenger-side trim panel in the luggage area. Proper seating of the holder ensures reliable contact and prevents intermittent lighting faults.

Common Failure Causes

Typical reasons for replacement include:

• Corrosion Of Contacts: Moisture ingress causes oxidation of terminals, leading to poor contact or intermittent lights.
• Mechanical Damage: Repeated bulb changes, impact or rough handling can crack the plastic housing or deform contacts.
• Heat Deformation: High temperatures from bulbs or poor ventilation may warp the socket and reduce contact pressure.
• Wiring Fatigue Or Breakage: Movement near the mounting point can wear the cable or break strands at the crimp.

How To Replace

1. Access The Lamp: Remove the rear trim panel or access cover behind the passenger-side seating area to reach the lamp cluster.
2. Remove The Lamp Assembly Or Socket: Depending on the vehicle trim, either remove the lamp assembly fasteners or reach the socket from inside and twist/pull the holder out of the cluster.
3. Disconnect Wiring: Carefully unplug the wiring connector or cut if required and prepare the new holder’s cable for connection. Ensure correct polarity and secure crimp/solder joints where used.
4. Fit The New Holder: Insert and lock the new holder into the lamp cluster until it seats firmly. Reinstall the lamp assembly and trim panels.
5. Test All Light Functions: Verify tail, brake and indicator functions before finishing. Replace bulbs with the correct types if necessary.

Installation Recommendations

• Disconnect The Battery: For safety and to avoid short circuits, disconnect the negative battery terminal before starting work.
• Use Dielectric Grease: Apply a small amount of dielectric grease to contacts to reduce future corrosion and improve longevity.
• Check Bulb Condition: Bulbs Are Not Guaranteed With The Part; Inspect Or Replace Bulbs During Installation To Avoid Repeat Visits.
• Secure Connections: Use Proper Crimps Or Solder Joints And Insulate With Heat-Shrink Tubing To Prevent Water Ingress.
• Verify Fitment: Ensure The Holder Locks Into Place And That The Cable Is Routed Free From Moving Parts.

Installation Guide

Recommended For Trained Mechanics And Competent DIYers:

• Open The Tailgate/Boot And Remove Interior Trim To Access Lamp Fasteners.
• Unscrew The Mounting Bolts And Carefully Pull The Lamp Assembly Outwards From The Body.
• Disconnect The Electrical Connector By Releasing The Locking Clip, Then Remove The Lamp Assembly.
• Install The New Lamp By Plugging In The Connector, Seating The Lamp Correctly And Replacing The Mounting Bolts.
• Test All Light Functions (Tail, Brake, Indicator And Reverse If Applicable) Before Reinstalling Trim.

Always Follow Common-Sense Safety Procedures: Disconnecting the battery is recommended when working on vehicle electrics to reduce risk of short circuits. Tighten fasteners to manufacturer torque where available and check the lamp alignment after installation.

Why The Part Most Commonly Fails

• Corrosion and Moisture Ingress: Water entering the lamp housing causes oxidation of contacts and poor conductivity.
• Heat Damage: Repeated heating from bulbs or over-wattage bulbs can deform plastic and degrade contacts.
• Mechanical Wear: Repeated bulb changes and vibration can loosen or fracture contact terminals and retaining tabs.
• Poor Electrical Contact: Dirt, loose connectors or bent pins cause intermittent operation and flickering lights.

Practical Tips

• When replacing the socket, inspect the lamp housing for cracks or seals that could allow water ingress and replace or reseal as needed.
• Test each lamp function after installation and verify good contact under vibration by gently moving the assembly while lights are on.
• Keep the OE product codes (6351N0, 6351T2, 9631563980) handy when searching for matching parts to improve findability and ensure correct fitment.
