Another approach might be to supply power to the ignition through a relay, then the engine compartment kill switch would break the relay trigger to kill the engine. Might not be a bad way to go if you have a lot of extra electrical stuff powered up (safeguard, electric fuel pump, other computers...) that could be fed off of that relay when the engine is running. Before
I converted all the way over to EFI, I was running the distributor less ignition with the stock carb, and ended up powering the
coil pack, safeguard, ignition portion of the EFI off of a single 40 amp 4 pin automotive relay and triggered the relay through the
existing stock coil feed wire- it triggered the relay any time the key switch was "on". It worked slick for years. I didn't think to
put a auxiliary kill switch in the engine compartment at the time -it sure would have been a simple thing to add though, and
is a really fine idea!!

It worked fine - I would not recommend this on a street car - It would make the car easy to steal! But for the race car, It made it easy to start and run the car - and turn it off -?from the engine compartment. Great for troubleshooting -somehow handy for a race car! For a street car and a powered distributor, you could interrupt the power connection to the distributor. On this distributor, that is the red wire connected to the positive (+) pole on the coil. As supplied, I install (crimped and soldered) a ring terminal on the wire end to insure retention. But you could easily replace that with a push-on spade-lug terminal pair. You could even use a type 56 GM terminal and single-cavity connector and make it look almost stock. Just yank it off to un-power the distributor, while leaving the ground and?coil control circuit a

At least the guy fessed-up to having done it, and a little while later a failure. - Seth Emerson?In a message dated 8/3/2015 8:30:49 P.M. Pacific Daylight Time, fastvair at yahoogroups.com writes:
