Description
DVD and multimedia player harness for Citroën C4 Picasso first generation.
This wiring harness is designed to restore reliable connections between the factory DVD/multimedia unit and the vehicle: power supply, grounds, speaker outputs, data lines and auxiliary audio/video inputs. Intended for professional mechanics and experienced DIYers, the harness corresponds to original part numbers 9656743980 and 6574C3 and provides a direct, OEM-compatible replacement to recover full multimedia functionality in Citroën C4 Picasso I vehicles. Using the correct harness reduces installation time and helps avoid intermittent audio/video faults caused by damaged or corroded wiring.
Technical Information

Fitment And Compatibility
Primarily fitted to first-generation Citroën C4 Picasso vehicles equipped with the factory DVD/multimedia assembly. Confirm that the vehicle’s head unit uses compatible connector layouts or the listed product codes before proceeding with installation.
Installation Recommendations
- Disconnect Battery Before Work: Always disconnect the negative battery terminal prior to removal or installation to protect vehicle electronics.
- Access Procedure: Remove center console trim and head unit securing screws to access the OEM harness connectors.
- Handle Connectors Carefully: Release locking tabs and avoid pulling on wires; inspect connector housings and pins for damage.
- Secure Routing: Route the new harness along factory paths, secure with clips or cable ties and ensure no tension or contact with sharp edges.
- Verify Electrical Protection: Check related fuses and grounds after fitting the harness.
- Test Before Reassembly: Reconnect battery and verify audio, DVD playback, steering wheel controls and any camera or auxiliary inputs before refitting interior panels.
Why The Part Fails Most Often
- Corrosion On Connector Pins: Moisture ingress leads to oxidation and intermittent contacts.
- Mechanical Damage During Repairs: Forceful unplugging, excessive bending or improper routing can break wires or terminals.
- Rodent Or Environmental Damage: Chewing, water ingress or debris can damage insulation and conductors.
- Loose Or Worn Contacts: Repeated disconnects and reconnects deform pins and cause poor signal transmission.
Additional Notes
The harness itself is a passive wiring component and typically does not require electronic coding. After installation, if multimedia functions remain impaired, inspect connectors, ground points and related fuses, and verify the head unit is operating correctly.
Order using OEM codes 9656743980 / 6574C3 to ensure correct fitment and restore factory multimedia operation in Citroën C4 Picasso I vehicles. Recommended For Professional Workshops And Experienced DIY Installers.
