Dwight youve got me confused.
If you ignored the colors of the wires, it is basically one wire that passes thru the kill switch on its way to wherever right? I know thats not exactly right but just to be simple.
so how can it matter which wire breaks? or are you saying the kill switch has two circuits going thru it, one for the ignition and one for everything else.
it would seem to me that breaking EITHER wire is no different then flipping the kill switch.
