So...that connector behind the seat is just a Canbus data connector so if you ever want to retrofit an OEM alarm that’s where it plugs in...
The alarm unit (BMW calls the module a DWA) is powered by a battery inside the module.
In addition if you ever install a Hex eZCan accessory controller for aux brake lights, driving lights, horn, etc. this is where you plug it in so it can access the bike’s body module controller.
