Yes, I tried calling MSD yesterday and they were closed despite it being normal working hours. I'll try again Monday.

the ground wire goes to the frame (not the battery). The power wire connects to a thick, main power wire that goes to the starter relay (it's a Ford, remember, so it's got those heavy relays that are wired directly to the battery, usually mounted on a fender). I do now know where the other end of that heavy wire is going to, I think the main fuse box. I'll double check. Then there's the switched power wire that goes to the ignition switch.

I do not have a heavy key chain, and the ignition switch feels solid. I've tried wiggling it a lot while driving and cannot cause the short manually.

I've checked the volts on the ground at that main starter relay and it's the same volts as the battery itself.
