I am also trying to locate this connector on the mp3 500.
From my research it appears to be on the nearside rear behind the battery on the underside of a frame member but have not been able to remove enough panels to expose this connector.
I'm in the process of installing a Piaggio alarm on my Yourban. I would like to know how to get to the alarm connection beneath the floorboards. More important how to remove the panels and in which order. Any help or guidance is appreciated.
