Description
Wiring harness for left and right rear tail lights for Citroën C8. Functionality of the bulbs themselves is not guaranteed.
This rear tail light wiring harness is designed for mechanics and DIY enthusiasts who need a reliable replacement for damaged or corroded wiring on Citroën C8 and compatible Peugeot models. The harness serves both left and right rear tail lights and is often searched for by the product code 6534KJ. Installing a new harness restores proper lighting signals, reduces flicker and intermittent faults, and eliminates the safety risk associated with poor electrical connections. Note that bulbs are not guaranteed to be functional and should be inspected or replaced separately.
Installation Recommendations
Before starting, disconnect the negative battery terminal to avoid short circuits. Typical replacement steps:
- Remove interior trim and access panels in the tailgate or trunk to reach the tail light assembly.
- Unscrew and remove the tail light units to access the connectors.
- Disconnect the old harness connectors from the tail light and vehicle body harness, noting clip locations and routing.
- Route the new harness following the original path, secure with clips or zip ties, and reconnect all plugs.
- Test all functions (tail light, brake light, indicator, reverse lamp, and side marker where applicable) before reassembling trim and panels.
Useful tools: Torx and Phillips screwdrivers, trim removal tools, pliers, multimeter for continuity checks, and electrical tape or heat-shrink tubing for final insulation.
Why This Part Fails Most Often
Common causes of harness failure include corrosion at connector pins due to moisture ingress, physical damage from impacts or improper removal, chafing where the harness rubs against bodywork, and rodent chewing. Vehicles driven in regions with heavy road salt or frequent water exposure are particularly susceptible. Faults usually present as intermittent lighting, blown fuses, or complete failure of one or more rear light functions.
