I put a 12v receptacle in both pockets. On the left side I built my own Y-connecter using molex connectors that I acquired from EC. Way cheaper than buying the $14.95 Y connector. The box on my '03 was marked for the hole.
On the right side I again made a custom wire harness that plugs into the heated grips power connector (I don't have heated grips) that buried down next to the airbox and above the vent. I also have a 12v receptacle in the trunk that works well.
For all of the connectors that I made, I hand crimped and soldered them. By building my own harnesses, I didn't cut into the factory wiring.
