This full-size crossover featuring an eight-passenger cabin was unveiled by Honda at the 2002 North American International Auto Show (Detroit). Unlike the Passport, which was based on the Isuzu Rodeo, this vehicle was engineered entirely in-house. Built on the same platform as the Acura MDX, it features more traditional SUV styling. In this article, we take a detailed look at the fuse box diagrams for the first-generation Honda Pilot (Mid-size SUV platform; code YF1 / YF2), produced from 2002 through 2008.
Below you will find power distribution box locations, layout diagrams, and photos. Fuse locations for the "Cigarette Lighter" and "Fuel Pump" are highlighted in bold.
