Most of the diagrams you find on the internet are either unreadable, or fit the bike of a different country (mostly the US version).
If you order this product you will receive a file by mail, size around 2 MB. The file contains a very well readable diagram of the UK an ED versions of the CB500K2.
With this diagram you can finally start the electrics project of your HONDA CB.
