I recently had a day that I was out riding but my cell phone died so I had to plug it into the accessory socket on the dash and run a cable into the glove box to hold my phone. With the cable there, the lid just didn't want to close properly so I knew I had to add a charging port to the glove box.
After looking at a few options I decided to use the
Blue Sea Systems Dual USB Charger Socket. Blue Sea makes great stuff and it is exactly what I was looking for. I added a pigtail. Here is the socket with the pigtail (minus the bullet terminals).
Next I had to figure out a location. I pulled the top left cover off and took the glove box out. Due to the solenoid on one side and the fairing on the other, the sides of the box were not an option; I had to use the front or back. Because of the design of the lid hinges, I wasn't going to be able to mount the socket anywhere except near the bottom. I had two options, relocate a relay that was hanging on a bracket behind the glove box (closest to the rider) or remove a metal bracket/tab that was welded to the subframe near the front of the glove box.
I decided to take off the metal tab. About 30 seconds with the dremel and it was gone. Touched it up with the file to remove any sharp edges and I had room to fit the socket into the glove box. In the photo I circled the bracket and the red line is approximately where I cut. This bracket seemed to only be holding the harness bundle away from the glove box lid hinges.
I marked the spot on the glove box and used a stepper bit to drill the 1.125" hole needed for the socket. I put the socket into the hole, tightened it up and then plugged it into the open accessory leads in the harness in the front of the bike. (picture of terminals)
I put everything back together and the glove box went back in with the socket installed in it. There isn't much room to spare. Here is the backside of the socket once everything was put back on the bike.
And the final product, closed, open and then with the 6" cable I have for my phone/scala.
Also, for anyone who wouldn't want a dedicated USB charging port, I believe the Blue Sea 12V socket is the exact same dimensions meaning it would fit in the same location.
