The accessory switch on the dash is powered by the plug under the seat. The plug has 4 pins numbered 1 thru 4. Does anybody know which # pin controls the switch and what are the other 2 pins for?
Thanks Quigley

No 1 is 12v when the key is on (o/r) No 2 is Brake light (r/y) No 3 is controlled by the accessory switch (o) No 4 is the ground (bk)

P.S. You have to install the fuse to power the switch

On my 06 Ultra, it has an accessory switch. I flip it on and off occasionally and nothing happens.... so I figure there must be another bike out there that has lights flashing on and off for no reason........

I have the same problem with a garage door opener,if anyone out there wonders why your door is operating on it's own contact me.
