• Harley-Davidson touring builds where rear speakers are being added
  
• Street Glide, Road Glide and Electra Glide audio upgrades
  
• Installations using the BC-9716 rear speaker harness
  
• Systems requiring the BC-9721 splitter as part of the rear speaker wiring
  
• Installers wanting to maintain an OE-style wiring approach

The key advantage is that it follows the factory Harley-Davidson backbone wiring configuration. When adding rear speakers, that gives installers a much cleaner route than fabricating an extension harness and makes the overall audio upgrade easier to service later.
