My big fat ugly fuse block protector
One thing I was not comfortable with was how exposed the fuse and fuse block were to the elements. The boots don't provide complete protection. Two yellow arrows, Picture 1.
So, I wrapped the whole fuse block assembly in 1.5 inch Shrinkflex (yellow arrow, picture 2), which is 2 to 1 heat shrink tubing for one layer of protection and to hold everything in place, especially the plastic fuse cover. Then enclosed the fuse block in 2 inch wire loom (blue arrow, picture 2) for water and mud protection. Pictures 2 and 3.
It's a bit ugly, picture 4, but I feel better knowing the fuse block is protected, just like the stock fusible link was pretty well protected in a plastic cover, wrapped and sealed.
I looked at other fuse blocks with plastic covers that totally encased the lugs, but they just seemed too flimsy, so I went this route, for now.
Remember to put the extra fuse in the glove box with a 9/16 inch wrench/socket, just in case you need to replace the fuse.
