It's kind of hard to tell from your picture because either my eyes have gotten even crappier, the picture is out of focus, or the doohickey in question has entered some sort of fuzzy quantum state. I think if you stick your multimeter probes in there you'll find there's 12 v available -- which points toward a strong possibility that's an "accessories" power source. There's often an accessory power source or two somewhere on (reasonably modern) bikes. Typically, they're under the seat, but if the PO was mistakenly convinced he or she was a motorcycle electrician, anything's possible! Your owners manual will tell you.
