I installed some PIAA's on my crash bars and used the PIAA switch but want to change that to the switches you are referencing. I have been looking for some real data on this and have discovered a few things.
The wiring on the 14's is different than the 13's.
Both the switches on the 14 RK are not in use and do not seem to be wired to power. (I'm going to take the whole headlight assembly apart to verify, this or next weekend depending on rain).
I have purchased 3 manuals for the 14 from HD adn none of them seem to detail the switches and any circuit they are on. The manuals are the standard 14 touring service manual, the standard 14 touring electrical service manual, and the 14 CVO supplemental manual.
I have spoken to 4 different dealerships about the wiring and none of them can give me any answers so far.
Ill post after take the headlight assembly off. I would appreciate it if you post anything you discover as well, good luck.
