Description
Wiring harness for the left and right rear lamps for Citroën C8 vehicles. Functionality of the bulbs is not guaranteed.
This used rear light wiring harness (part number 6534KJ) restores electrical connections for both left and right tail lamp assemblies on Citroën C8 and compatible Peugeot 807 vehicles. It is targeted at professional mechanics and experienced DIY enthusiasts who need a direct replacement after connector damage, corrosion or accident repair. Replacing the entire harness is often faster and more reliable than splicing individual wires when connectors or insulation are compromised.
Technical Information
- Manufacturer: Stellantis / Citroën
- Model: Citroën C8; compatible with Peugeot 807
- Product Codes: 6534KJ
- Other Numbers: NFP
Installation Recommendations
Before starting, always disconnect the vehicle battery and follow the manufacturer’s removal/installation procedure to avoid damage. Typical replacement steps:
- Open the tailgate and remove interior trim to access the rear lamp fixing screws.
- Unscrew and carefully withdraw the lamp assembly to reach the wiring connectors.
- Unplug the original harness connectors and release any retaining clips or grommets along the bodywork.
- Route the replacement harness along the original path, secure it with existing clips or new cable ties, and ensure grommets are seated to prevent water ingress.
- Reconnect all plugs, refit the lamp assembly, and test all lamp functions (tail, brake, indicator, reverse) before reassembly.
Use dielectric grease on exposed connectors to reduce corrosion and improve contact. If connectors or lamp holders are heavily corroded or damaged, replace them prior to completing the installation.
How To Replace
Replacement is straightforward for an experienced technician: remove the lamp unit, unplug the old harness, transfer any mounting clips to the new harness, fit and secure the new harness, then test all functions. Allow circa 30–90 minutes depending on access and whether interior trim must be removed.
Why This Part Fails Most Often
Rear lamp harnesses typically fail due to moisture ingress and corrosion at connectors, mechanical damage from impacts or chafing against bodywork, thermal ageing causing brittle insulation, or rodent activity. Faults present as intermittent lights, blown fuses, or complete loss of one or more lamp functions.
Notes
Bulbs and lamp holders may not be included and their functionality is not guaranteed. Inspect connector fit, contact condition and sealing before final assembly.
Benefits
Fitting a complete rear harness restores reliable electrical continuity, reduces recurring faults caused by corroded connections and speeds up repair time. Suitable for repair shops and competent DIYers seeking a direct-fit solution for Citroën C8 rear lamps.
