Unless the small grounding wire (can see in the first pic) counts as the second wire, it only has one. OK, here's where I'm a little confused. I see a small wire coming from under the flywheel and it goes to the throttle control. Looks like #356: 'wire-ground found here. I'm assuming the ground wire in this case is the same as the kill wire? Is that wire no longer needed because the new kill wire will be connected to the same spot? It connects right behind the tube in the second pic. Sorry for the focus, I couldn't get the dang camera to focus where I wanted it to. How does the kill switch work? The part to which it connects doesn't seem to move any, and I don't see anything that makes a connection to ground it out.
