Most power supply circuits in this sedan are protected by fuses. High-current components—such as headlights, cooling fan motors, and the fuel pump—are routed through relays. Protective fuses and relays are housed in power distribution boxes located under the hood and in the passenger compartment.
This fuse diagram information applies to 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, and 2003 model year Mazda Xedos 9 / Millenia (chassis code TA) models.
