Description
Wiring harness for left and right rear lamp for CITROËN C4 5-door first series. Functionality of the bulbs themselves is not guaranteed.
This replacement rear lamp wiring harness is designed for the Citroën C4 5-door (first generation) and provides a reliable connection between the vehicle electrical system and the left and right rear light clusters. Ideal for professional mechanics and DIY enthusiasts, the harness restores proper power, ground and signal paths for stop, tail, indicator and reverse lamp circuits when the original loom is damaged, corroded or has intermittent contacts.
Benefits
– Direct-fit design for hassle-free installation on compatible C4 models.
– Restores electrical continuity and improves safety of rear lighting circuits.
– Useful spare for collision repair, water-damaged lamps or corroded socket connections.

Installation Recommendations
1. Remove the tail light assembly according to vehicle service procedure (usually access from the boot/tailgate area).
2. Disconnect the battery negative terminal before working on the wiring to avoid short circuits.
3. Unplug the old harness from the lamp sockets and vehicle connector; note clip and grommet positions.
4. Fit the new harness, ensuring correct alignment of pins and secure seating in rubber grommets to maintain water protection.
5. Reassemble the lamp cluster and test all functions (tail, stop, indicator, reverse) before finalizing the installation.
6. Use dielectric grease on terminal contacts if corrosion is suspected and replace damaged clips or seals to prevent water ingress.
Why This Part Fails
Rear lamp wiring harnesses typically fail due to corrosion and water ingress at the connector or lamp socket, mechanical damage from impacts, chafing against bodywork, rodent bites, or brittle wiring insulation caused by heat and age. Loose or bent pins cause intermittent contact, resulting in flashing or non-functioning lamps. Regular inspection for moisture and corrosion can prevent many common failures.
This harness is a practical, cost-effective repair option for restoring rear lighting function on Citroën C4 5-door first series vehicles. Always verify visual compatibility with the lamp assembly and follow standard safety procedures during replacement.
