EQUIPMENT DEPENDENCY
Seat wiring looms are highly specification dependent.
Discovery 4 front seats can have different electrical equipment including:
• Electric fore/aft adjustment
• Seat height adjustment
• Backrest adjustment
• Lumbar adjustment
• Driver memory functions
• Seat heating
• Seat control modules
• SRS / seat airbag connections
• Seat belt / occupancy-related circuits
Not every AH22-series seat loom supports exactly the same equipment.
TECHNICAL INFORMATION
The seat wiring harness distributes electrical power and control signals between the vehicle wiring and electrical components installed within the driver’s seat.
Depending on vehicle specification, connections can include:
• Seat adjustment motors
• Seat adjustment switches
• Memory-seat electronics
• Seat control module
• Lumbar adjustment system
• Heating components
• SRS-related components
• Seat belt-related connections
The loom uses factory-style connectors and routing designed for the original Discovery 4 seat assembly.
SEAT ELECTRICAL SYSTEM INFORMATION
The Discovery 4 electrically adjustable seat system contains several separate motors and electrical components.
The wiring harness provides the electrical connection between these components and the vehicle’s electrical network.
Damage to the loom or individual connectors can therefore cause one or several seat functions to stop operating.
COMMON REASONS FOR REPLACEMENT
• Broken or damaged wiring
• Damaged electrical connectors
• Corroded connector terminals
• Intermittent electric seat operation
• One or more adjustment motors not operating
• Memory-seat functions not operating correctly
• Wiring damaged during seat removal
• Previous seat repair or replacement
• Damaged SRS-related seat wiring
IMPORTANT DIAGNOSTIC INFORMATION
Before replacing the loom, check:
• Seat fuses and power supply
• Electrical connectors underneath the seat
• Seat adjustment switches
• Individual adjustment motors
• Seat control module
• Wiring continuity
• Earth connections
• Stored diagnostic fault codes
A non-operating electric seat does not automatically mean the wiring loom itself is faulty.
INSTALLATION
The seat normally needs to be loosened or removed to access and correctly route the complete wiring harness.
Disconnect the vehicle battery and follow the appropriate Land Rover procedure before disconnecting any SRS-related seat connectors.
Route the replacement loom exactly as originally installed and ensure wiring cannot become trapped in the seat runners or adjustment mechanisms.
PROGRAMMING / CODING
The wiring harness itself does not normally require programming or coding.
However, diagnostic work may be necessary if SRS or seat-control fault codes are stored following a wiring or component fault.

Do not assume that every Discovery 4 electric driver’s seat uses the same wiring loom. Connector quantity, electrical equipment, memory functions, heating and other seat options can change the harness specification.
Compare the complete part number and every electrical connector with your original loom before ordering.
