In 1980 I bought my CB500, first registered in 1977. No Owner's Manual under the seat, so I asked Honda The Netherlands if they could send me one. They sent me this one:
http://www.honda4fun.com/pdf_libretti/500/CB500_k1/CB500_K1_1.pdf. Although that booklet contained no less than four wiring diagrams, none of them applied to
my model; they all showed
one fuse where my model had
three.
Not until last week - 38 years later - I got the appropiate wiring diagram for the CB500K2 (ED)*. I had informed on the French and the German site before, but it is thanks to the
fratelli of the Italian site that I now have it in a readable resolution.
What strikes me, is that the wiring diagram says:
CB500 WIRING DIAGRAM (U.K.- EUROPEAN TYPE).
Now the diagram clearly applies to
my model: it shows the three fuses and also depicts the
not connected and useless LB/W and O/W wires that are in the bucket of my headlamp which the US CB5
50s used for running lights. Now correct me if I'm wrong, but I always thought that the CB500K2 (ED) model was
not imported in the UK. Anyway, if it
was and if any of you need the correct wiring diagram, send me a PM. BTW I'm still on the lookout for that model's wiring diagram for the French and the German type to make
them happy, although I do not think they will differ much. If any of you happens to have this CB500K2 Owner's Manual:
http://www.honda4fun.com/pdf_libretti/500/CB500_75/libretto500_1.pdf,
http://www.honda4fun.com/pdf_libretti/500/CB500_75/libretto500_2.pdf http://www.honda4fun.com/pdf_libretti/500/CB500_75/libretto500_3.pdfthe three wiring diagrams are in the last pages and I would be much obliged if someone could scan also the French and German one in a readable resolution. There are some strange things in that Owner's Manual btw, but that's another story.

It's my believe that this model and also the later CB500K3 served to empty the Honda shelves of leftover 500cc engineblocks.
