Description
Wiring harness for the left and right rear tail lights for Citroën C8 vehicles. The functionality of the bulbs themselves is not guaranteed.
Product Overview
High-quality used rear tail light wiring harness for Citroën C8, supplied as a pair covering both left and right sides. This harness carries all power and signal circuits to the tail light assemblies (brake, tail, indicator, and reverse where applicable). Ideal for mechanics and DIY enthusiasts who need a direct replacement part with original connectors and routing for a correct fit.
Technical Information
- Manufacturer: Citroën / Stellantis
- Model: Citroën C8, Peugeot 807
- Product Codes: 6534KJ
- Additional Numbers: NFP
Function And Fitment
This wiring harness provides the electrical connections between the vehicle body loom and the rear light clusters. It ensures correct signalling for tail lights, brake lights, indicators, and reversing lights (depending on vehicle equipment). The harness typically uses original manufacturer connectors and mounting points for straightforward installation on Citroën C8 and closely related platform mates such as the Peugeot 807.
Common Failure Causes
- Corrosion at connector pins and terminals due to moisture ingress.
- Mechanical damage from impacts, trunk loading, or improper removal/installation.
- Wire fatigue or chafing where the harness is routed over sharp edges.
- Rodent damage or chewing in older vehicles.
- Oxidation or loss of contact at bulb holders (note: bulb functionality is not guaranteed with this harness).
Installation Recommendations
- Always disconnect the battery before starting work and follow the vehicle manufacturer’s removal/installation procedure to avoid damage.
- Access the tail light assembly by removing the interior trim or luggage compartment panel to reach the harness connector and mounting points.
- Unplug the existing connector from the lamp unit, release any retaining clips or grommets, and free the old harness while observing the original routing.
- Fit the replacement harness following the same routing, secure with OEM clips or cable ties, and ensure grommets are seated to prevent water ingress.
- Before final assembly, reconnect the battery and test all light functions (tail, brake, indicator, reverse) with a helper or using a test lamp/multimeter.
- If any circuit shows high resistance or intermittent operation, inspect and clean connector pins or replace the harness as required.
Why Replace The Harness
Replacing the rear tail light wiring harness is commonly required when connectors corrode, wires break, or the harness sustains physical damage preventing reliable signaling. Symptoms include intermittent lights, blown fuses, or non-functioning rear lights. Using an original-style replacement harness restores correct connections and eliminates splicing that can lead to future faults.
Notes For Professionals And Enthusiasts
This is a used original-equipment harness supplied as shown. Bulbs and lamp units are not guaranteed to be functional with this harness. Verify continuity on suspect circuits with a multimeter and inspect connector integrity during replacement to ensure long-term reliability.
