Malibu, looks like a nice set up, but you might want to change your switch at some point in the future to a waterproof switch.
My tractors are garage kept, but I have been caught out in the rain and I've found that spending $8 on a waterproof marine grade submersible switch is worth the money because I never have to worry about them failing. I also use weatherproof in line fuse holders on my wiring because I don't want a little rain to get inside the standard units and corrode them out. The weatherproof units cost about $1 more than the standard units. Just a thought.
