I don't have the time, money, or patience to gut the thing and and install a whole wire harness, but I can put in a nice sub panel. I've used these fuse blocks on several other projects in the past, mostly motorcycles.
It has a built in relay, 6 circuits, and you can make any of the 6 be switched of constant hot just by where you plug in the fuse.
