You're welcome!

No, having the redundant connection to the starter solenoid "R" terminal won't hurt anything or cause any extra current draw. It's basically just providing 2 paths for battery voltage to reach the HEI while cranking the engine.

As long as the ignition switch is powering the HEI through the pink wire in both the "run" and "start" positions, having the yellow wire from the starter solenoid "R" terminal really isn't necessary. But having it there won't hurt anything either.
