Description
Complete antenna harness for Peugeot 407 vehicles.
This antenna cable assembly (OE references 9655815280 / 6561V1) is designed to restore reliable radio reception and a secure connection between the roof/door antenna and the vehicle radio unit in Peugeot 407 models. The harness is aimed at professional workshops and experienced DIY mechanics who search by part number or need a direct replacement for a damaged or corroded antenna lead. Correct installation ensures stable AM/FM reception and avoids intermittent loss of signal caused by poor contacts or damaged wiring.
Technical Information
- Manufacturer: Peugeot (Stellantis)
- Model: Peugeot 407
- Product Codes: 9655815280, 6561V1
- Other Numbers: NFP (as listed)
Function And Application
The harness transmits radio-frequency signals from the vehicle antenna to the head unit. It typically includes one or more coaxial leads, connector plugs that match the radio and antenna base, and routing clips to secure the cable along the vehicle body. On Peugeot 407 vehicles the assembly is used for factory radio systems to guarantee consistent reception and a stable mechanical connection between aerial components.
Replacement Procedure (Overview)
Recommended steps for replacing the antenna harness (general guidance; follow vehicle-specific manual):
- Disconnect The Battery: Always isolate the battery before starting work on vehicle electrical systems to avoid short circuits and unintended airbag deployment.
- Access The Antenna Base: Remove necessary trim panels or headliner sections to reach the antenna base (roof or rear) and the route of the existing harness.
- Disconnect Connectors: Unplug the antenna connector(s) from the antenna base and from the radio/head unit. Note connector orientation and retaining clips.
- Remove The Old Harness: Free the cable from clips and grommets, pulling it carefully through the same routing path to avoid damaging surrounding trim or seals.
- Install The New Harness: Route the new harness along the original path, secure with existing clips, connect to the antenna base and to the radio, ensuring connectors are fully seated.
- Test Reception: Reconnect The Battery and test radio reception on multiple bands. Reinstall Trim Panels After Confirming Proper Function.
Installation Recommendations
- Use Dielectric Grease Sparingly On External Connectors To Reduce Corrosion And Improve Long-Term Contact.
- Secure The Cable With Original Clips Or Equivalent Fasteners To Prevent Rubbing And Mechanical Stress.
- When Removing Headliner Or Trim, Work Carefully To Avoid Creasing Or Breaking Retaining Tabs.
- Check The Antenna Mast And Base For Corrosion Or Mechanical Damage When Fitting A New Harness.
- Verify Connector Types Match The Radio; Many Installations Are Searched By OE Number (9655815280 / 6561V1) — Use This For Fast Identification.
Most Common Failure Reasons
- Corroded Or Oxidised Connectors Leading To Intermittent Or Poor Reception.
- Cable Damage Due To Water Ingress Around The Antenna Base Or Through Seals.
- Mechanical Wear From Repeated Movement (Doors, Roof, Or Improper Routing) Causing Broken Internal Conductors.
- Poor Or Loose Connections At The Head Unit Or Antenna Plug Resulting In Signal Loss.
- Damage From Body Repairs Or Accidents Where Clips Or Grommets Have Been Disturbed.
Choosing the correct part number (9655815280 / 6561V1) and following recommended routing and sealing practices will maximize service life and restore stable radio performance in Peugeot 407 vehicles.
