The Toyota Land Cruiser 100 replaced the 80 Series, which had demonstrated exceptional reliability over the years. Consequently, the global popularity of the 100 Series was largely driven by the tremendous success of its predecessor. In this article, we will take a detailed look at the fuse box diagrams for the sixth generation Toyota Land Cruiser (J100 / J105 chassis codes) produced from 1997 to 2002.
Here you will find the locations and photos of the junction boxes. The fuse responsible for the “Cigarette lighter” is highlighted in bold.
