MSD 6A battery kill switch wiring

If running the blue/brown wires looped together to turn on your MSD, run those wires back to the cutoff small stud and a wire forward back the the MSD. Throw cutoff, the energy to the MSD switched wires goes dead, car turns off.

Run the fuel pump relay trigger off the same side as the wire heading back to MSD, kills that too...

Not my favorite way to do things, but works.
