That's the fuse box, mines mounted different, looks like yours or mine is inverted, i.e. lift it up off the rubber mount, remove the cover should be 4 fuses 3 10a 1 20a. On mine i pull the cover off looks like your cover is @ the bottom (cover is on the top, not the 8 wire plug on mine) so you want a spare 10a and a 20a. Unless US models are different.
