I would like to change my Thumb throttle which currently has an on/off switch and 3 led battery level indicator lights to a key one to stop people from switching it on when I’m not about ie parked outside shops or pub.
The only thing is my current thumb throttle has 6 wires going into the controller connector and the one I want to replace it with has 5 wires!
Can this still be done?
