Great work, thanks for sharing. Using info from your video and others I managed to plug the connector for the USB without removing the side fairing. I just used a screwdriver to unhook the connector and some pliers to pull it out. Not an easy job because you have to fit both your hands between the fork arm and the fairing, but can be done. Afterwards I fitted the wires in the connector in the right position and just pushed it in with one hand. Ride safely!
I do not have access to a 2013 model, so I do not have sure info. However I made some research and seems, the OP (options) connector underneath the seat has different pinout on the 2013 model, so that part is different. Regarding the connector for the accessory socket I could not find any reliable info, sorry.
