The DR650 has two unused 'switched' power plugs. One behind the headlight and another under the seat. This plug & pigtail assembly allows you to easily access a 12v power supply that is only on when your key switch is on.
Use it to power a GPS, charge a cell phone, run heated grips or even power a relay. Plug has leads approximately 1 foot long and a 7.5 amp miniature blade fuse.
