Land Rover Part Number: LR021818 - Auxiliary Fuse Box
LR021818 is an auxiliary fuse box fitted to the vehicle body electrics on the Defender. It houses fuses, fuseholders and relay positions that distribute and protect secondary electrical circuits for lighting, accessories and other ancillary systems. The unit connects to the vehicle wiring looms via multi-pin connectors and relay sockets and is designed so that a blown fuse or failed relay only affects the specific circuit, making faults easier to locate and repair. Replacement must match the vehicle wiring harness and connector layout to ensure correct routing and secure connections; routine checks of fuse condition and connector seating reduce the likelihood of intermittent faults.
