So the person that sold it to you did not know . That means he did not buy it new. . The baby story often used by flippers to soften up a buyer.
There maybe many surprise on that bike

I knew he was not the original owner. I also found out the reason he didn't ride it and has to sell. He bought it in January then got a dui in February so he is not allowed to drive for over a year. Apparently his dad took it out once in awhile just to get it moving. Everything else on the bike seems fine. Rides good, starts and runs great. Its just the mystery button lol.

Is it a momentary switch, or on/off? That might give you a clue as to it's function. What color are the wires where it enters the harness? Does it look like the wires were part of the original harness? You can get a wiring diagram in color from H-D. See if the colors correspond to anything on the wiring diagram.

Here you go, Zippy!

Good luck!

Its a momentary switch, I used one when I installed my garage door opener on my RK, if it does nothing I would remove it.
