Actually: SM-2 is the correct signalMinder. and a little costly but a set of Kuryakin lights is more and won't stop that truck from running over the top of you when you finally turn the wrong way and get smucked
The switch is already one that returns to the center so I think it doesnt need any modifications.
I also found out that for hooking up the running light option:
signalMinder harness Black wire to Left side turn signal wire of the bike ??
signalMinder harness White wire to Right side turn signal wire of the bike ??
signalMinder harness Red wire to Brake side turn signal wire of the bike Green
This image did not show the turn signal bulbs so I can't show those colors. However there should be only two wires for the turn signal bulb. And it's NOT the Red/white wire because that's ground.
Will have to modify the switch as well but - good rainy day project !
