How did you do that?

I hooked up a switch on the dash next to the glow switch, that connects to a vacuum solenoid. Touch the switch and vacuum is routed to the shutdown on the IP which shuts down the engine. To bleed the vacuum I put a pinhole in the line to allow a quick restart. It has worked perfect for the past 55k miles. A better option however, is to use a switchover valve that will dump vacuum to atmosphere automatically. One of these days I'll switch it but for now, since it's not broke, I'll wait to fix it.

What you need is a 3 port, 2 way solenoid valve. The 3 ports allow it to bleed vacuum when in the "vacuum removed" mode so the shut off is ready to reapply. I got mine from Peter Paul but it was a bit hard to order. If you go that way I can look up the part number.

Sometimes the instrumentation plumbing that I did in my working life comes in handy!
