Key on wire for MSD ignition and one wire alt

Hmmm,if ya say so. But my resources clearly show a wire from starter relay to positive side of coil via ballast resistor. Wired my junk this way forever and no problems. How can power in the load circuit of a relay possibly energize said relay?

1..........Post "my resources". Mine are the factory service manuals

2..........I'll ignore that

3...........Really? OK I will explain.

The starter relay has two "push on" connectors. ONE of them is powered from the "start" wire coming from the key, often yellow colored. It powers the relay for cranking, and that is the ONLY thing that wire does

The GROUND side of the relay is only activated on 70/ later stick cars when you push in the clutch. On automatics, it's grounded in neutral or park.

THIS MEANS that the power to the ignition system (the "ignition run") which is HOT will FEED BACK over your "starter relay" wire and PROVIDE POWER TO THE STARTER RELAY. If the clutch is depressed, or if the automatic is in neutral or park, the relay WILL HAVE A GROUND PATH, and since it has power coming in from the ignition wire, IT WILL ENGAGE the starter.
