Wiring the kill switch turned out to be easier than I had anticipated. Of course I realized what was up after I loosed the fuel tank and removed the shroud, thus making the job much harder. Anyway, the coil already has a wire going from the spade terminal to an insulated screw/terminal on one of the heat shields. Turns out that all I had to do was run a wire from the kill switch to this insulated terminal which allows the kill switch to short the coil to ground. Here's some pics:
The switch was spray bombed silver like the rest of the bike. This paint preserved the switch's finish. I cleaned it in solvent and gave it a nice polish with the Dremel:
Here's the switch installed:
And finally, the insulated terminal and wiring:
One last note, I was sure to loosen all of the head bolts then torque them back to 200 in-lbs. Seems to run the same as it did prior to this operation. I guess Tecumseh makes some good head gaskets.
