So. I have a Ducati plug to sae connector on the bike. This should have enough output for Garmin sat nav and also a USB adaptor to charge the phone.? Thinking to join in to the new wires (splice/solder and seal) to use the garmin cable with the 12v to 5v box on the cable and a cable to usb. This should reduce the need for multiple wires. Not worried about it being permanent live as I will not leave the sat nav on the bike. I would like also to fit Daytona heated grips (the ones with built in switch on left grip) wired via the white connector under the black cover, left side at headstock.12v and switched I think. Does this sound reasonable? Kept me awake last night thinking of the least messy way for the wiring. Plan to use Garmin bracket on a Ram mound on left handlebar and have a Shad tanklock type bag, where I want my phone charging lead to go. Probably bring cables under the tank and out near ignition/head stock.
