Where does this go?

[pscook]

I am installing an e-start on my 2011 300. I have the entire wiring harness, so I am sorting out what goes where. Right now I have an extra wire as well as a couple of questionable ones.

Let's cut to the chase- Yellow wire with green tracer with 8mm ring connector. It terminates from the wire harness at the coil, but the only thing that has a ring possibility is the ground lug next to the coil (where the zener diode/regulator mounted). Where does it go? Is it necessary? Here's a pic of the offending piece-



Also, off the stator are two wires- One yellow and one white. They seem to line up perfectly with a white and yellow wire in the harness, but they were not very close and I had to maneuver the bits to get them to meet. Should the plug in? See below-



Last question (for now...), on the bar switch with the rotating knob, stop, and horn buttons- The signage is worn, so I can't see exactly what each position on the knob performs. Does this knob affect running? I am not getting spark (even with the key on), and I want to eliminate the variable of the knob. Suggestions/diagrams/pictures are appreciated for chasing no spark.
