How do you change main fuse in 2006 Mazda 6?

The fuse block under the hood needs to be raised. There are four tabs around the perimeter of the block. There are 2 small bolts that hold the fuse in place. Remove the 10mm bolts then simply pull out the fuse and replace it, reinstall the bolts and place the fuse block back in place. There are sliding guides that will align the block.
