Can you explain to my non-technical mind, how that Indian USB Speedo Mount Kit works. Does it replace any of the parts on the OEM speedo (e.g. I have a bronze speedo cap)? I assume there’s a USB connection at the speedo that you run the wire from? Is that where the power comes from because there’s an extra powered accessory connection there? Or, do I wire to the battery? Does it not draw ANY power when bike is shut off because it’s fused/switched? Thanks for any help you can provide.
