As I recall, the fuse relocator was essentially a fuse replacement that had wires that shunted outside to an external holder. So I sacrificed two fuses to make two. I cut the fuse metallic element, soldered wires to each end, wrapped the things to provide mechanical strength, and ran the wires outside to external holders. So the relocators act just like fuses, and can be removed, and replaced with fuses if you like. No mods to the machine, no soldering, and very servicable.
I believe the old relocators were this principle. Any geezers like me out there care to chime in?
