Genuine used Land Rover roof wiring loom / headlining wiring harness, removed from a 2010 Land Rover Discovery 4 L319 3.0 TDV6 Diesel.
This wiring harness runs within the roof/headlining area of the vehicle and provides electrical connections for roof-mounted equipment. The exact connectors and supported equipment can vary depending on the vehicle specification, so please compare the complete loom, connectors and engineering number with your original part.
Part Number / Engineering Number: AH22-14334-EO
Part Type: Roof Wiring Loom / Headlining Wiring Harness
Application: Roof / Headliner Electrical System
Position: Interior Roof / Headlining
Manufacturer: Land Rover / JLR
Condition: Genuine Used Part
Donor Vehicle:
Land Rover Discovery 4
Chassis: L319
Year: 2010
Engine: 3.0 TDV6 Diesel
Right-Hand Drive UK Vehicle
Compatibility:
Suitable for Land Rover Discovery 4 L319 vehicles where the original roof wiring harness carries the matching AH22-14334-EO engineering number and matching connector/equipment configuration.
Typical vehicle application:
• Land Rover Discovery 4 / LR4 L319
• Approx. 2010-onwards applications
• 3.0 TDV6 / SDV6 diesel models where fitted
• 5-door SUV body
• RHD and potentially LHD vehicles depending on wiring specification and equipment
IMPORTANT: Roof wiring looms can differ according to model year, trim level and optional equipment. Compatibility should therefore be confirmed primarily using the AH22-14334-EO number, connector layout and fitted equipment, rather than vehicle model alone.
Technical Information:
The roof wiring loom forms part of the vehicle’s interior electrical harness and distributes electrical connections through the headlining/roof area.
Depending on vehicle specification, the roof harness may provide connections associated with equipment such as:
• Interior / courtesy roof lighting
• Front overhead console
• Reading lamps
• Roof-mounted sensors
• Alarm system components
• Microphone / hands-free equipment
• Sun visor or vanity mirror lighting
• Rear interior lighting
• Other roof-mounted electrical equipment
Not every Discovery 4 uses the same roof harness configuration.
Roof Electrical System Information:
Land Rover produced different wiring harness specifications depending on the equipment installed at the factory. Vehicles equipped with additional roof electronics may require a loom with extra connectors or different wiring branches.
For this reason, two Discovery 4 vehicles from the same year and with the same engine can still use different roof wiring looms.
Common Reasons for Replacement:
• Damaged or cut roof wiring
• Broken connectors
• Previous headlining removal damage
• Electrical faults affecting roof-mounted equipment
• Interior lighting faults caused by damaged wiring
• Loom damaged during accident repair
• Replacement after interior or roof repairs
• Corrosion or connector damage
Important Diagnostic Information:
Before replacing the loom, check the relevant fuses, connectors, earth points and individual roof-mounted components.
Electrical faults can sometimes be caused by a failed component rather than the wiring harness itself.
Inspect your original loom carefully and compare the connector quantity, connector shapes, wire branches and engineering number.
Installation:
Installation normally requires partial or complete removal/lowering of the vehicle headlining and associated interior trims.
Care should be taken when removing trim panels and electrical connectors to avoid damaging the headlining, clips or wiring.
Professional installation is recommended where required.
Programming / Coding:
The wiring loom itself normally does not require programming or coding.
However, individual electronic modules or optional equipment connected through the loom may require configuration or diagnostic procedures depending on the vehicle specification.
Important Compatibility Note:
Please match AH22-14334-EO with the number on your original wiring loom wherever possible.
Also compare all plugs, connectors, mounting points and wiring branches with the photographs before purchasing.
Do not rely solely on vehicle registration, engine size or model year, as Discovery 4 roof wiring configurations can vary according to factory-installed equipment.
Condition:
Genuine used Land Rover part.
As a used wiring loom, it may show normal signs of previous installation, storage and removal. Please check the photographs carefully for the exact condition, connector configuration and included wiring branches.
