Land Rover Part Number: LR121421 - Repair Wiring Overlay
LR121421 is a Repair Wiring Overlay that connects into the main body electrical system as an overlay repair harness where sections of the main wiring require repair rather than a full harness replacement. The unit provides a pre-formed section of wiring and connector interfaces to restore electrical continuity to specific circuits without removing the complete main harness; conductor cores, terminal crimps and protective sleeving match the routing and connector types used in main body overlay harnesses. Installers should verify connector orientation and secure routing to prevent chafing or moisture ingress after fitment. Use the compatibility data below to confirm fitment against your V.I.N.
Compatibility
- Range Rover (2013 - 2022) - L405
