i have seen 3 different types of switches that can be mounted on the bars. 2 of them mount straight to the bar on the side of the on/off switch, the 3rd one actually mounts to the OEM yamah on/of switch, im not understanding how thats possibly since there is 3 functions on the unit and its not like a cap on top can be removed and replaced with a switch, can someone explain this to me please? All 3 are the same price... anyone have picstures of the switches mounted on the bars and which ones? i was thinking about drilling a hole in the hood for a switch but dont want to and i dont want to have a switch inside the hood compartment.. thanks!
