The Subaru Impreza made its debut in December 1992. The model was offered in front-wheel drive (FWD) and all-wheel drive (AWD) variants, with available body styles including a four-door sedan and a five-door station wagon (Touring). In this article, we provide a detailed overview of the fuse box diagrams for first-generation Subaru Impreza models (GF, GC chassis codes; 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, and 2000 model years) equipped with 1.5-liter EL15, 2.0-liter EJ20, and 2.5-liter Turbo EJ25 engines.
Below you will find fuse box locations, component layouts, and panel photos. Fuses protecting the “Cigarette Lighter” and “Fuel Pump” circuits are highlighted in bold text.
