The 500 lack of multiple fuses is there a cure ?

I would not. The better alternative of course is the loom the CB500K2 (ED, F, G) had: https://www.cmsnl.com/honda-cb500k2-general-export_model50441/harness-wire_32100374700/
BTW, it's the same the CB550K2 (A) had. You can have 3 fuses, knowing: 15A main, 7A head, 5A tail.

What is the advantage of using this loom over the one Ken mentions?
Part number appears to be 32100-374-700 not currently available at csml - DS show as discontinued.
Oddjob:
Advantage Ted would be the ignition would be in the right place with the K2 loom.
Must admit Ted to not thinking this through enough, I used a scrap 550F2 that I bought as a write off, funnily enough the lad I bought it off only moved in 2 doors away from me last year, haven't seen him since 1980, I was polishing some parts on the front when he passed and the part I was polishing was off his old bike, strange world.
Anyway, I had to use the electrical panel off the 550 as well due to it having the facility to hang the fusebox off, something I didn't think about until you mentioned where to put it.
I hindsight it might be better to go with the Motogadget, they don't float my boat but they seem to work.

So how does the Motogadget connect into the existing loom or do you bin that then individually connect each device into the box of tricks or is it a Canbus system?
Is there a good video that shows the way?

Ted, I'm not saying this is a great video but may help https://www.youtube.com/watch?v=gsSNS91EmxU&ab_channel=CafeRacerGarage
CanBus is a little more complex than the Motogadget and seems to be simplified but certainly ideal for bike re-wiring. I would not install it if I didn't need to rewire, however. I do like the idea of an imobiliser and alarm built in. I also like hazards on a bike - I'm sure Roo will chip in!! ;D

Motogadget is just remote switching on solid state control board as I understand it, so command switch to tell the board to turn the required circuit on, power then runs to device from there, without going through switch. A relay system in essence, just integrated to one unit.
Canbus, principle is the device has a constant supply from live loom (for example a brake light) with a control method sighted at that device to toggle it on/off. The signal to do that comes from ecu command sent "consentric" down that wire as a digital code to "call" that responding unit in situ. The ecu can then control all the devices by having their unique address.
Effectively can be one ring loop of positive to all components (deletes all individual strands) to remove much wiring etc. Can also monitor status, resistance etc to observe any out of range component.
Household computer comms with Ethernet over mains effectively does the same in sending digital data through live 240 volt distribution concurrent to other usage.
