Antenna wiring harness for Citroën C1, Peugeot 107 and Toyota Aygo
This antenna wiring harness is a direct-fit electrical lead set designed to connect the vehicle antenna base to the factory radio in Citroën C1, Peugeot 107 and Toyota Aygo models. It restores a reliable signal path for AM/FM reception and provides the correct connector interface for original equipment radios. Ideal for professional workshops and DIY mechanics who need a straightforward replacement part that fits the factory routing and connectors.
Technical Information

- Product Codes: 86101-0H020, B000699880
- Additional Numbers: NFP
Compatibility
Designed for factory-fitted antenna systems used on Citroën C1, Peugeot 107 and Toyota Aygo. Often searched by part number (86101-0H020 / B000699880). Verify visual match of connectors and routing during fitment.
Function And Symptoms
The harness transfers the antenna signal from the roof or antenna mast to the radio unit. Typical symptoms of a failing harness include weak or intermittent radio reception, static or loss of one or more bands (AM/FM), and visible damage at connector points. Replacing the harness usually restores reception without requiring changes to the radio.
Installation Recommendations
- Disconnect the negative battery terminal before starting work to avoid short circuits when handling electrical connectors.
- Gain access to the antenna base (roof or rear pillar) by removing the relevant trim panels; take care with plastic clips to avoid breakage.
- Inspect the antenna mast and base for corrosion or water ingress while the harness is exposed.
- Unplug the old harness at both the antenna base and the radio. Route the new harness following the factory path and secure with original clips or equivalent fasteners.
- Ensure connectors are fully seated and that any coaxial inner conductor is not crushed. After installation, test radio reception and verify there is no unwanted noise.
Most Common Cause Of Failure
Failures are usually caused by moisture ingress and corrosion at connector joints, mechanical damage from worn or chafed wiring where the harness passes through body seals or under trims, or impact damage to the antenna base. Long-term exposure to road salt and vibration accelerates wear.
Service Life And Advice
There is no fixed replacement interval; a properly installed harness can last many years. Replace if reception degrades, connectors show corrosion, or wiring insulation is damaged. When replacing, also inspect the antenna mast and base for damage—faults there can mimic harness failure.
Notes For Mechanics And DIY Enthusiasts
This is a plug-and-play wiring harness for vehicles using the original-type antenna connectors. Keep the part numbers handy (86101-0H020, B000699880) when searching or ordering to ensure a fast match. Use trim tools to remove panels without damage and secure the harness to avoid rattles or wear points after installation.
