the black wire from the distributor with the female side of the plug is the negative! I hooked it up, started the engine, and it fired right up.

I was pleasantly surprised, because I don't have an RPM chip in the MSD6AL and didn't know if it needed one just to run, and I wasn't positive that I had the distributor wires hooked up correctly.

so, either the black wire IS the negative, or, it doesn't matter how it's wired up, because it's running fine as-is.
