r80rt did his set up almost exactly as I did mine. Only difference is that I used a splitter type of outlet. It has a double socket(cigarette type) and a double USB. The splitter had a folding 'arm' that would plug into the car's 12v outlet. I removed that to give me a nice size modual with the ability to plug in 4 things at once! Had to split it open and solder some wires as I removed the swivel plug. Ran 14GA wires to the battery, through a relay, that also sends power to the heated grips. Getting back to the 'modual', I too mounted it to the side of the pilot light box, however I used 3M tape rather than put a hole in it. As I do know something about voltage and the regulation of said voltage I can tell you that almost all of your expensive electronics only need about 5v to charge. The modual that I modified had the vital electronics in the 'box', not the swivel. I can plug in 4 things to charge, (GPS, Iphone, helmet coms,and tablet)and draw about 5 amps. For my air pump, I ran a second 12v outlet that is mounted to my front rack. It has also been modified. Extending the wires long enuff to go directly to the battery, I used a battery tender extension wire that I plug into the fused Battery Tender pigtail. Yes, this makes it 'hot' all the time. If I need to hook up the battery tender, I unplug the 12v socket, and plug it in as normal. I even mounted the exact same voltage meter in the same place. All this being said, it all works for me, your results may vary.go slow and test it as you install it. TIM
