For owners of Mazda RX-8 models manufactured between 2004 and 2011, we have the fuse box diagrams you need. These handy illustrations show the locations of all the fuses within the vehicle, close to the driver’s side. They act as the electrical system’s defenders, making sure everything functions properly—from lamps to stereos. Thus, check your fuse box schematic before you start tinkering—it’s your road map to a purring RX-8!
Cigar lighter (power outlet) fuses in the Mazda RX-8 are the fuses #1 “CIGAR” (Lighter), #3 “AUX PWR” (2003-2008: Accessory socket), #13 “OUTLET” (2009-2011: Accessory socket) in the passenger compartment fuse box, and fuse #8 “ACC” (Lighter, Accessory socket) in the engine compartment fuse box.
