Description
Wiring harness for the left rear door behind the driver for Citroën Berlingo K9 and Peugeot RIFTER, plus other Stellantis models
Part description
Used left rear door wiring harness 9828029980 connects the door components electrically to the vehicle’s wiring system. It is a suitable solution when replacing damaged door wiring, for example if wires are broken, insulation is damaged, or connectors are damaged.
Replacing the complete matching harness can make repairs easier than repairing individual wires and connections. When selecting a part, compare in particular the product number 9828029980, connectors, wiring branches, and design of the original part. A matching model name alone does not necessarily mean that the door wiring is the same.

Installation recommendations
The following procedure is a general guide to replacing a door wiring harness. The exact procedure for removing the trim, disconnecting the connectors, and routing the wiring depends on the specific model and vehicle configuration. Follow the manufacturer’s service procedure.
1) Before installation
- Compare the part number, length and branching of the harness, connector shapes and configurations, fuses, grommets, and mounting points with the old part.
- Inspect the insulation along its entire accessible length. Pay particular attention to worn, hardened, pinched, or previously spliced areas.
- Check the connector contacts for bending, being pushed in, corrosion, or heat damage.
- First verify the cause of the fault. Similar symptoms can also be caused by a faulty connected component or a damaged mating connector.
2) Tools and materials required
- Standard hand tools suitable for the fasteners used, and plastic trim removal tools.
- A suitable tool for carefully releasing connector locks.
- A multimeter for checking disconnected wiring according to the wiring diagram.
- Labels and a camera to record the original wiring route.
- If required, a product suitable for electrical contacts and appropriate wiring fasteners.
3) Step-by-step installation procedure
- Park the vehicle safely, switch off the ignition, and secure the door to prevent it from moving unexpectedly while you work.
- Allow the electronics to enter sleep mode and disconnect the battery according to the vehicle manufacturer’s procedure.
- Remove only the trim and covers needed to access the harness. Refer to the service procedure for the exact method of releasing the clips.
- Photograph the original wiring route, the position of the grommets, and the mounting points for each branch. Label the connectors if necessary.
- Release the connector locks and disconnect the connectors by holding their housings. Do not pull on the wires or pry at the contacts.
- Gradually remove the harness from its clips and grommets. Check the route for sharp edges, dirt, or anything that may have caused the original damage.
- Place both harnesses side by side and compare their design again. Do not force mismatched connectors to fit or improvise connections.
- Route the replacement harness along the original path. Preserve natural bends and provide enough slack where the wiring flexes as the door moves.
- Seat the grommets correctly and secure all branches. The wiring must not interfere with moving mechanisms or be trapped beneath the trim.
- Connect the connectors and check that their locks are engaged. Before switching on the power, check that no connection is loose or incorrectly connected.
- Reconnect the battery according to the manufacturer’s procedure and perform a functional check before refitting the trim completely, if conditions allow this safely.
- Install the covers and trim, then check the operation of the connected components again and make sure the door moves freely.
4) Post-installation checks and function verification
Test all electrical door functions connected through the harness for the vehicle’s equipment level. Repeat the checks at different door positions: functions must not cut out, and the harness must not be stretched or pinched. Check that the grommets, clips, and trim are seated correctly. A stationary vehicle is generally sufficient for checking the harness itself; only perform a test drive after the installation is fully complete and the door has been checked to close securely.
5) Common installation mistakes and how to avoid them
- Selecting a part based only on the vehicle model: also compare the part number, connectors, and harness branching.
- Pulling on the wires: always release the connector lock first and grip the connector by its housing.
- Incorrect wiring route: use photos of the original routing and all designated clips.
- Stretched or pinched wiring: check the full range of door movement before completing the installation.
- Grommets not seated correctly: carefully check that they are properly seated to limit moisture ingress and wire chafing.
- Failure to address the cause of the original fault: repair damaged mounting points or a fault in a connected component, otherwise the problem may recur.
Reasons why the part may become damaged
The following are common causes of damage to door wiring harnesses in general; they do not describe the known condition of the item offered:
- Repeated bending as the door moves, which can gradually cause wire fatigue and breakage.
- Chafing or pinching of the insulation due to incorrect harness routing or loose mounting.
- Moisture in the connectors and subsequent contact corrosion, for example if a grommet is damaged or not seated correctly.
- Careless removal, particularly pulling on the wires and damaging the connector locks.
- Short circuit or electrical overload caused by a fault in the connected circuit.
- Aging insulation and poor-quality previous repairs, which can reduce the flexibility and reliability of the wiring.
