I've already mentioned why you use a relay here.

No, it didn't have one stock, but they also didn't come with HEI distributors stock that require 12+v for proper operation.

Maybe your blank state comment isn't assuming HEI, but I'm not sure what you meant by that.

I had the same problem.
I would have to look at the diagram to explain where the back feed was from but it had to do with the alternator and the resistance wire. If you don't want to
completely rewire the circuit there are some threads on installing a diod to stop the back feed. The relay coil does not have enough load to drop the voltage low enough for for it to drop out when the key is turned off.

The power is completely gone from the trigger wire when I turn off the key. I still can't figure out why it's not letting go. If I pull the trigger wire it goes off. And if I tap the rely I can her it trigger and I trigger but once it starts it won't release.

Relays can go bad and the contacts stick. New doesn't necessarily mean operational either.
