switch

I got my buddy's small Toro snowblower running but i cant get the kill switch to work. I got another switch that wasnt a direct replacement so i spliced it into the existing lines. That didnt work either. So i took the ground wire and touched it directly to the wire that runs behind the shroud...

Heres a very hard to find part thats always missing. This is a chrome kill switch plate that was on the Cat 400X. This is placed on top of the frame in front of the seat. Top is in excellent condition with 1 minor ding and the bottom has light surface rust that should clean up well. $35

I need kill switches for 3 mini bikes what kind is good. some look cheep. What kind do you use. what is good?

I am done with my clone install and I am wondering what wires to hookup to the kill switch on the handlebar. Is it the two wires coming from the switch on the engine, just splice them up? One ground and the other one.
