Monster 1200s 2016 USB power source

Hi all,

Looking to mount a usb charging point to my handle bars somewhere so I can charge phone, sat nav etc. I have found an un-used connector under the front left hand side of the tank that I believe can be used for this purpose. Does anyone know what connector I would need, it’s not one I have seen before?

Failing that, I charge the battery via the DDA plug under the seat using the optimate DDA to SAE lead, could I simply use a SAE to usb connector and run it to the bars? I have read conflicting thoughts on using the DDA as a continual power source.

Cheers
