Mazda Bongo (also sold as the E-Series and Access) is a cabover van produced by Japanese automaker Mazda starting in 1966. Depending on the powertrain layout, it was manufactured in rear-engine, mid-engine, and front-engine configurations. This article provides detailed fuse and relay box diagrams for fourth-generation (SG chassis) Mazda Bongo Friendee and Brawny models produced from 1995 through 2005.
Below are the locations, diagrams, and photos of the power distribution boxes. Fuses for the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold.
Fuse configurations vary across Mazda Bongo models. Always verify circuit assignments against the diagram printed on the inside of the fuse box cover.
