1. not sure about the TORS since mine was already removed when i bought my banshee, but i think you unplug a black box somewhere and remove the wires coming from the thumb throttle. someone else will chime in and help out with that one.
2. yes, they come with key switches
3. all banshees have pretty much the same wiring except the later ones that have a brake light instead of taillight
4. no indicator lights
