There is no factory auxiliary power plug on a Speed Triple. The only free plug that should be hanging under the airbox is the lead for the California-only charcoal canister, which is a sensor lead that does not have 12 volts to it.
You'll have to wire a power point from the battery somehow. I recommend an ignition switched power point. You can pull power from the tail light circuit to energize the solenoid.
...also, only püssies use GPS.
