Function And Application
- Provides electrical connections between the vehicle wiring loom and the driver seat: motors for fore/aft and recline, lumbar adjustment (if fitted), heated seat elements (if fitted) and seat occupancy/airbag sensors.
- Includes connectors and protective routing to accommodate seat movement and maintain reliable contact during normal use.
- Used on Peugeot 308 T7 front driver seats; exact features depend on the vehicle equipment level.
Replacement Procedure (Summary)
Replacement should be performed by a trained technician or an experienced DIY mechanic following safety precautions. Basic steps:
- Disconnect the negative battery terminal and wait a few minutes to ensure systems are powered down.
- Move the seat to a position that allows access to mounting bolts and trim.
- Remove seat trim panels and covers to expose the harness routing and connectors.
- Unplug all seat connectors, noting their positions and securing clips. Release any cable retainers and remove the old harness from the seat frame.
- Install the new harness following the original routing, secure with clips and retainers, and reconnect all plugs firmly.
- Refit seat trim and mount the seat, tightening bolts to the manufacturer’s specified torque values.
- Reconnect the battery and verify seat functions and airbag/occupancy system status. Clear any stored fault codes as required.
Installation Recommendations
- Always Disconnect The Battery Before Starting Work To Prevent Airbag Deployment And Electrical Damage.
- Handle Airbag And Occupancy Sensor Connectors Carefully; Avoid Pulling On Wires—Use Connector Bodies.
- Replace Any Damaged Clips Or Grommets To Prevent Chafing And Future Failures.
- Use The Manufacturer’s Torque Specifications For Seat Bolts And Fasteners.
- After Installation, Perform A Functional Check Of Seat Motors, Heating Elements (If Present) And Verify No Airbag Or Seatbelt Fault Lights Remain.
