This might have been done before but I'm going to post it ( I joined the site about 3 months ago after working on Brits-Triumph and BSA), I picked up a 78 CB550 and wanted to try and keep it original as possible and this worked out pretty good. A Dremel, female terminals, solder, and some patience. I picked up an extra fuse block from E Bay and used it for this and kept the original from the bike
