The Mazda 626 was based on the Capella model, produced primarily for the Japanese domestic market (JDM). It replaced the 616/618 and RX-2 models in 1979 and remained in production until 2002. Offered in sedan, hatchback, and station wagon body styles, even base trim levels featured a generous level of standard equipment. In this article, we examine the fuse box diagrams and panel layouts for the fifth-generation Mazda 626 / Capella (GF chassis), covering model years 1997, 1998, 1999, 2000, 2001, 2002, and 2003.
Below are the locations, diagrams, and photos of the power distribution centers. Fuses for the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold for quick reference.
In the Engine Compartment
The engine compartment contains one primary fuse box along with individual relay modules.
