Description
Complete front passenger seat wiring harness for Peugeot 3008 T84 and 5008 T87 vehicles.
This complete front passenger seat wiring harness (part reference 6545XX) is a direct-fit replacement designed for Peugeot 3008 (T84) and 5008 (T87) models. Ideal for professional garages and DIY mechanics, the harness restores all electrical functions located in the passenger seat — including airbag and belt buckle sensors, seat position motors, heating elements and occupancy sensors where fitted. Manufactured for Stellantis / Peugeot platforms, this durable wiring loom helps eliminate intermittent faults caused by damaged or corroded seat cabling and speeds up seat repairs or replacements.
Technical Information
- Manufacturer: Stellantis / Peugeot
- Model: Peugeot 3008 T84, Peugeot 5008 T87
- Product Codes: 6545XX
- Other Numbers: Not Specified
Function And Compatibility
The harness links the passenger seat electrical components to the vehicle wiring: SRS (airbag) circuits, seatbelt buckle switch, seat occupancy sensor, electric seat motors (fore/aft, recline, lumbar) and seat heating circuits if the vehicle is equipped. Compatibility is aimed at the specified model codes (T84 / T87) and will match seats with the same connector layout and equipment level. Verify connector shapes and pin counts when replacing to ensure full functionality of all seat features.
Replacement Procedure
- Disconnect the negative battery terminal and wait at least 10 minutes to allow SRS capacitors to discharge.
- Move the seat to gain access to mounting bolts, then unbolt and remove the seat from the vehicle following manufacturer torque and removal sequences.
- Carefully release and unplug all seat connectors (airbag/SRS, belt buckle sensor, motors, heaters). Mark connectors if needed to avoid confusion during reassembly.
- Remove the old harness, noting routing and securing points. Install the new harness along the same route, secure with clips/retainers and avoid sharp edges or pinch points.
- Reconnect all connectors, refit the seat, torque mounting bolts to manufacturer specification and perform a full system check (SRS indicator, seat adjustment, heating and belt buckle detection).
Installation Recommendations
- Always disconnect the battery before touching airbag-related wiring and wait the recommended time.
- Use the original attachment points and cable ties to prevent chafing and movement; avoid excessive bending of the wiring loom.
- Inspect connectors and mating pins for corrosion or damage; replace connector housings or terminals if worn to ensure reliable contact.
- After installation, run a diagnostic scan with a suitable tool to clear any fault codes and verify SRS and seat electronics operate correctly.
Why The Part Most Commonly Fails
Seat wiring harnesses typically fail due to mechanical wear: repeated seat travel causes chafing at fixed points, creating broken conductors. Moisture ingress and corrosion at connector pins, accidental damage during seat removal, previous improper repairs and impact damage from collisions are also common causes. Over time, flexing of wires at the harness exit points can lead to intermittent faults affecting airbags, seat heaters or adjustment motors.
Notes For Professionals
Replacement of the passenger seat harness should be performed by a trained technician when possible. After fitting, confirm SRS integrity and all seat functions via a diagnostic tool and follow Peugeot repair procedures for torque, connector retention and post-service checks.
