Magneto question

[GWGAllisfan]

On a cast iron single: I have a new magneto for my engine so I can convert it back to the points ignition. I have a question about the wiring. This coil has two wires, one is bare, the other insulated. I assume the bare one is to be attached to the bolts that hold the coil one, just to be sure it grounds. on my old coil that was the wrong one ( a magnetron , not compatible with the flywheel) one wire went to a bolt that went through the back plate of the housing. A wire ran from this to the kill switch. I assume this bolt is insulated, but I don't know. so do I run the wire from the coil to the points then jump a wire to the kill switch? or run to this bolt and one one wire from this bolt to the points and another to the switch?

The bare wire is the ground for the coil. The insulated one connects to the point stud. The 'kill circuit' is from the points to a normally open PB or ignition switch, open to run, then to ground. When either switch is closed and circuit is shorted.
