I have the original resistor wire going to a relay, triggering a full 12-14 volt feed with the key on.
Thanks for the kill-switch idea - been thinking of adding something like that.

The White/Purple/Orange resistor wire from the bulkhead connector on the firewall, is designed to increase resistance as it heats up in use. Going from full 12 VDC down to 7 VDC to not burn up the points. In an HEI system points are gone, and you need the full constant voltage at 12 VDC. If this lead is wired to trigger a relay, there is a possibility that the decreased voltage, [as resistance increases], may be insufficient to keep the 12 volt relay closed. This could cause an intermittant feed to the Coil.
Nice concept, but too complicated for an ignition circuit. They should be simple.
