I just installed one on my '13 Ultra, can't imagine it would be much different. Use the "Y" connector, it is essentially a splice to the tour pack lights. No need to go all the way to the battery. Locate the 3 pin connector near the front of the tour pak on the hinge side. You unplug the existing connector, install the "Y" and re-connect the existing wire to one leg of the "Y". The other leg is for the lead coming from the Air Wing light. You have to build up the connector on the air wing lead once the wire is routed into the tour pak. That was the trickiest part of the installation and requires a special crimping tool for the pins. No need to spend the outrageous amount of money HD asks for a Deutsch crimper, you can use a D-sub crimper for these. You can pick up a D-sub crimping tool at Radio Shack for about $10. You might want to pick up a strip of pins to practice the crimp on if you've never used one before. Be careful not to crush the hump on the pins that came with the kit, that is what holds them in the connector. Once the crimping is done and the pins installed in the proper cavities of the connector housing just plug the new connector into the remaining leg of the "Y" harness, secure your wiring and your good to go. Good luck!
