When I swapped in a 617 to my 107, I had to design a shutoff since the ignition switch didn't have the vacuum shutdown valve. I used a vacuum switchover valve and a momentary push button switch for shutdown. This also allows me to remove the key and lock the car with the engine running if desired. It's rarely needed, but nice option to have.

It's the perfect companion to the manual glow plug switch.
