Wiring experts needed.....

Ok, I've made some progress (I know, I need to post pics, I'll get some soon, it does look bad azzzzz), anyway, I'm wiring the new motor up and have run into some problems. As you can see in these attached drawings, typically I would run the yellow wire to the MSD box to enable it to start. But, I'm going to run a mini starter, and they don't have the R or relay pole a standard chevy starter has. What I "think" happens, is that when starting, the coil gets 12V from the R post on the starter and when started and ignition switch is put to the run position, the 20P (depending on year, this example is from a 64, 65 has white/orange/purple) becomes hot with 12V and continue's to run the coil.?.?.? That's what I see from this diagram. So if I don't have a R pole on the starter, I'm thinking I may have to get an automotive relay, and run that off the S pole on the starter (16PPL) and run the contacts to the yellow wire, and the yellow wire also to the MSD box. This would provide a temporary, starter circuit hot to the MSD when starting. Does any of this make sense to anyone else? Am I on the right track?

Thanks.
