Snakewolf,
Installing the kill switch simply shuts off the current to the wings motor. So when the wing is in its "auto mode" it won't go up automatically between 60 and 65 mph. An audible alarm will still sound at speeds of approximately 90 mph to let you know the wing is not activated, at a speed where it's truly needed.
Once you activate the switch to it's "on" position, the wing will operate in it's normal manner, and automatically come back down at speeds of around 35 mph.
Manual mode will only operate as long as the on/off switch is in it's on position.
