Interesting, i have a 250 2t evo 2013 and the map switch plastic box was a bit busted up so i decided to just remove it and join the wires. According to the beta owners manual when the yellow switch is pushed down thats the hard setting for dry, whereas when the switch is in the up position its soft for wet. So i broke the switch open and it looks to me like when the switch is in the hard position the wires are joined. I have since decided to redo it and get a handlebar on/off switch so i can try both settings to see if there is any difference.
