Toyota Land Cruiser 100 and Toyota Land Cruiser 105 were produced in 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007. During this time, the model has been restyled. In this publication, we will show the location of the electronic control units, a description of the fuses and relays of the Toyota Land Cruiser 100 (105) with box diagrams and their locations. Highlight the cigarette lighter fuse.
The location of the boxes and the purpose of the elements in them may differ from that shown and depends on the year of manufacture and the region of delivery.
