Unveiled at the January 1999 North American International Auto Show in Detroit, the XYR concept car was created at Toyota’s Calty Design Research studio in California. The XYR previewed the seventh-generation Toyota Celica, introduced during a period of shifting automotive market trends. This article provides detailed fuse box diagrams and relay assignments for the 7th-generation Toyota Celica (chassis code T230; MC platform) for model years 1999, 2000, 2001, 2002, 2003, 2004, 2005, and 2006.
Below are the component locations and photos of the power distribution centers. Fuses for the “Cigarette Lighter” and “Fuel Pump” circuits are highlighted in bold.
