The exact wiring loom fitted can vary according to seat position, electric adjustment specification, memory-seat equipment, heating and other seat options.
For this reason, compatibility should primarily be confirmed using 4H22-14A614-FA / YMQ501730 and by comparing all connectors and wiring branches with the original loom.
Technical Information:
The front seat contains several electrically operated components. The seat wiring harness provides the electrical paths required to connect applicable components to the vehicle electrical system.
Depending on vehicle specification, connections may include:
* Electric seat adjustment motors
* Seat adjustment switches
* Seat control components
* Seat power supply
* Seat heating equipment
* Memory-seat equipment where applicable
* Associated seat sensors and electrical connections
Not every vehicle uses every connection because the harness configuration depends on the equipment fitted to the seat.
Electric Seat System Information:
The harness routes electrical power and control signals through the seat assembly to the relevant electrical components.
Damage to the loom can cause individual seat functions to stop operating even when the seat motor or adjustment switch itself remains serviceable.
Common Reasons for Replacement:
* Damaged or cut seat wiring
* Broken electrical connectors
* Wiring damaged during seat removal
* Intermittent electric seat operation
* One or more adjustment motors not responding
* Corroded or damaged terminals
* Replacement seat supplied with an incorrect loom
* Repair or restoration of the original powered-seat system
Important Diagnostic Information:
If an electric seat function has stopped working, the relevant fuse, power supply, earth, adjustment switch, motor and wiring should be checked before replacing individual components.
Inspect the harness carefully around moving sections of the seat frame, as wiring can potentially become trapped, stretched or damaged by seat movement.
Installation:
Designed to follow the original routing through the compatible front seat assembly.
During installation, ensure that:
* All connectors are fully secured
* Wiring follows the original routing
* Harness clips are correctly positioned
* Wiring is kept away from moving seat rails and mechanisms
* No cables are trapped beneath the seat frame
The battery should be disconnected according to the correct Land Rover procedure before working on seat electrical systems, particularly because the seat assembly can contain SRS/airbag-related electrical connections.
Programming / Coding:
The wiring loom itself does not normally require programming or coding.
However, vehicles equipped with memory seats or additional electronic seat modules may require appropriate diagnostic procedures if control modules are replaced separately.
Important Compatibility Note:
Please match 4H22-14A614-FA / YMQ501730 with your original wiring harness before purchase.
Land Rover used multiple front-seat wiring configurations depending on model, production year, left/right seat, memory function, heating and seat equipment level.
Please compare the part number, electrical plugs, number of connectors, wiring branches and overall harness layout with your original part. Vehicle model and year alone should not be used to guarantee fitment.
Condition:
Genuine used Land Rover OEM part. Normal age-related marks may be present from previous use and removal. Please inspect all listing photographs carefully, particularly the connectors, wiring and mounting clips.
Genuine Land Rover front seat wiring loom – ideal replacement for a damaged or faulty 4H22-14A614-FA / YMQ501730 harness on a compatible Discovery, Range Rover Sport or Freelander seat system.
