I want to wire in a Kill Switch to my Ignition. There are two wires going into my Coil, can I run a switch to both of them (keeping the circuits separate) or should I ground the coil? Also, what gauge wire should I be using>

Thanks in advance.

Here is a pic of the coil. The two wires I am talking about are the solid black wire and the black wire with a white stripe. Do not worry about the yellow wire, that is a ground wire which is how the kill switch is wired at the moment.

What I am talking about is removing the ground wire and just putting a switch in either one or both of the black wires. Any suggestion for and/or against this. If I was only to cut one, which one?

As an experiment remove the wire for the battery side with the engine running. The engine should stop. If that's the trick, just put your switch on that.
