Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: Citroën C5 I Estate, Citroën C5 II Estate
- Product Codes: 6534JZ
- Other Numbers: NFP
Compatibility And Applications
Fits rear lower lamp assemblies on Citroën C5 I (first generation) and Citroën C5 II (second generation) Estate/Kombi body styles. Ideal for replacing a damaged lamp harness after rear bumper removal or light cluster repair. Always confirm physical connector shape and mounting points before installation.
Function And Typical Fault Symptoms
The harness provides electrical connections and bulb sockets for the lower rear lamp, delivering power, ground, and retaining the bulbs in the lamp housing. Common symptoms of a failing harness include intermittent lighting, blown fuses, melted or discoloured connectors, visible corrosion on contacts, or complete loss of the affected lamp function. Wiring damage after a minor collision or persistent water ingress are frequent causes.
Replacement Procedure
- Prepare: Park on a level surface, engage parking brake, and disconnect the negative terminal of the battery before any work on the electrical system.
- Access: Remove interior trim from the tailgate or trunk side panel to reach the rear light cluster and harness routing. On some models the bumper or lower trim may need partial removal for clear access.
- Disconnect: Unclip and unplug the harness connectors from the lamp cluster. Remove retaining clips or screws that secure the harness to the bodywork.
- Swap: Replace the damaged harness with the new unit, routing it along the original cable path and refitting all clips and grommets to maintain sealing against moisture.
- Test: Reconnect the battery and test all rear light functions (brake, tail, turn, reverse as applicable) before reassembling trim. Ensure connectors are dry and secure.
- Finalize: Refit interior panels and any removed trims. Verify lights again after a short test drive.
Installation Recommendations
Use dielectric grease on connector pins to slow corrosion and improve contact reliability. Replace any cracked grommets or damaged clips to maintain a watertight route. When routing the harness, avoid tight bends and places where abrasion against body panels can occur. If bulbs are old or show signs of overheating, replace them at the same time to avoid recurrent connector damage.
Why This Part Commonly Fails
Failures Most Often Result From Corrosion And Water Ingress, Mechanical Damage From Impacts, Or Connector Overheating Due To Poor Contact. Over Time, Road Moisture And Salt Can Penetrate Seals And Degrade Contacts; Vibration And Physical Strain Can Cause Wire Breaks Or Detached Sockets.
