You might check out the several threads on yellow bullet. The summary of "wisdom" contained in them seems to be this: Run a heavy output wire from the alternator to the battery side of the cutoff switch (there is a chart at the top of their electrical forum; 20 ft at 60 amps max for 4 gauge). Run the MSD power to the battery directly. Solder and crimp connections. The reasoning is this: The alternator (brushes) make the output noisy so don't power the MSD there. So long as the "trigger" is cut off by the switch, the car will stop running. Don't cut the alternator with the switch or you can blow the diodes. I ran 2-0 gauge from the battery to the switch and from the switch to the front (junction block). Hope this helps.
