If you have the 4 post battery switch as in your picture. Just run the charging system as it is wired originally and use the small posts on the battery switch to shut off the ignition system. Just run the ignition activation wire through the small posts. When the switch is shut off the ignition also shuts off. Engine stops running.
Hope this helps, Digger73 (Mike)
This is how i did mine but ran MSD ground wire to battery switch. Not NHRA legal, but it turned the engine off.
