Take the seat off.
At the rear of the bike, near-side on the left when viewed from behind the bike, close to the seat catch, there is a blanked-off socket, cable tied to the undertray.
It doesn't look like the usual diagnostics socket. It's not for the alarm. Can't see any mention of it in the owner's manual. Anyone know what it's for?

Saying that my dynamic pro socket was extremely well hidden.
