When I got my first Borg Warner R10 (installed in a '57 Chevrolet) I had to completely remake the wiring harness from scratch. I never knew there was fuse, but after reading I've read where there should be a 20 amp fuse in the harness. Where should this fuse be located? Would inserting a 20 amp blade style fuse holder with blade fuse be acceptable?

Thanks,
Brandon
