Suitable for vehicles with the corresponding front-seat specification and identical wiring connections.

Compatibility is determined primarily by seat specification, electrical equipment and loom number, rather than engine size.

TECHNICAL INFORMATION

The seat wiring harness distributes electrical connections between components installed within the front seat assembly.

Depending on the vehicle’s seat specification, the harness can interface with equipment such as:

• Electric seat adjustment components

• Seat adjustment motors

• Seat control electronics

• Heated seat components

• Seat adjustment switches

• Seat belt / occupancy-related connections

• Memory-seat equipment where fitted

• Vehicle electrical supply

The exact connections fitted to the loom depend on the original seat specification.

ELECTRIC SEAT SYSTEM INFORMATION

Discovery 4 L319 vehicles were available with several different front-seat configurations.

These can differ according to:

• Manual or electric adjustment

• Heated-seat equipment

• Memory-seat specification

• Lumbar adjustment

• Seat motors fitted

• Occupant/restraint equipment

• Model year and trim specification

For this reason, a Discovery 4 seat loom should not be purchased based only on vehicle year or engine size.

COMMON REASONS FOR REPLACEMENT

• Damaged or cut seat wiring

• Broken electrical connectors

• Corroded terminals

• Intermittent electric seat operation

• One or more seat motors not operating

• Heated-seat electrical faults

• Previous incorrect seat repair

• Damaged wiring underneath the seat

• Replacement required during seat conversion or refurbishment

IMPORTANT DIAGNOSTIC INFORMATION

If an electrical seat function is not working, check the complete circuit before replacing the harness.

Inspect:

• Seat fuses

• Main seat power supply

• Earth connections

• Electrical plugs and terminals

• Wiring for cuts or trapped sections

• Seat adjustment switches

• Individual adjustment motors

• Seat control module where fitted

• Heated-seat components where fitted

• Diagnostic fault codes

Wiring can become damaged or trapped underneath an electrically adjustable seat, particularly around moving seat-frame components.

INSTALLATION

Correctly route the replacement wiring through the original seat-frame mounting and retaining points.

Ensure the harness cannot become trapped or stretched when the seat is moved through its full adjustment range.

The battery should be disconnected according to the correct Land Rover workshop procedure before disconnecting front-seat electrical components.

SRS / SAFETY INFORMATION

The front seat assembly contains wiring associated with the vehicle’s occupant restraint system.

Take particular care when disconnecting any SRS / airbag / seat belt-related connectors.

Professional installation is recommended.

PROGRAMMING / CODING

The wiring harness itself does not normally require programming or coding.

However, if seat control modules or other electronic components are replaced at the same time, additional configuration or diagnostic procedures may be necessary.

IMPORTANT COMPATIBILITY NOTE

Please match the complete number from your existing wiring harness:

AH22-14A578-AA

Also compare:

• Number of connectors

• Connector shapes and colours

• Wiring branches

• Seat equipment specification

• Motor connections

• Heated-seat connections

• Memory-seat equipment where applicable

Discovery 4 uses several different seat wiring looms. For example, AH22-14A699-AGA is separately catalogued as a Discovery 4 passenger-seat wiring harness, confirming that different seat positions/specifications use different harnesses. (Global Parts)

Do not assume that another Discovery 4 seat loom is interchangeable simply because the connectors appear similar.

CONDITION

Genuine used Land Rover OEM wiring harness.

Removed from a 2010 Land Rover Discovery 4 L319 RHD front right / driver’s seat.

Please inspect the listing photographs carefully and compare all connectors, wiring branches and AH22-14A578-AA part number with your original harness before ordering.
