* Online Forums: Search Honda motorcycle forums (like Honda-tech, or more general motorcycle forums). Someone may have scanned a diagram and posted it, though this is rare due to copyright. Be prepared to search thoroughly using various keywords.
* Used Parts Websites: Sometimes used parts websites (like eBay) will have listings for service manuals that include wiring diagrams. While the manuals aren't free, they might be cheaper than buying a new one. Look for scans or digital downloads rather than physical books.
* Library Resources: Check your local library or university library. They might have access to Clymer or Haynes manuals which often include wiring diagrams.
* Manuals from Dealers: A Honda dealership *might* provide you with a partial schematic, or point you towards a source for a manual, but this is unlikely to be completely free.
Important Note: Be extremely cautious when using diagrams found on unofficial sources. Incorrect wiring can severely damage your motorcycle's electrical system or even be a safety hazard. If you lack electrical experience, it's best to consult a professional mechanic. A small investment in a reliable manual is far less expensive than fixing electrical problems caused by an inaccurate diagram.
