Good band!!
Kill switch....engage!!!!
Anyway, the switch should of come with instructions. Without knowing what it wants to do it's hard to give advise. In VERY basic terms, it's going to work like the run/stop switch. Your monkey ass goes flying and by a rip cord or pressure switch something kills the juice/grounds out. There are alot of ways and places to do it, which is why if you post an exact model, I or someone else can help.
