My speedo has a white wire with a green stripe That im told i can use for a signal to switch from launch mode to shift mode. Sitting still the bike will be in launch mode and when the bike is rolling the speedo has a sensor that will send a signal down the wire to the turn signal relay. This is all i have herd about this and before i splice the wire i would like to know more about how it works and will it work for my shift light.
