V8 Topic: "simple" HEI wiring is not so simple to me, but I'm seeing light at the end of the tunnel... Options

Car was wired for the 283 with all standard components down to a stock Chevy starter (Jaide kit). external coil, resister, etc.

My "Continous improvement plan" was to bolt in a built 357, HEI dist with high volt integral coil, Renegade high torque starter, and high amp alt. Of course I've missplaced all the component instructions and Renegade wants to sell their $200 harness so I went and researched this with varying information.

HEI.
I have an HEI with integral coil. There are only two connections, Battery and Tach

BATT
1. From what I understand this connection replaces a resister and must to be 12 or 10 GA with constant 12 volts at key ON. Can the Black/Red wire from the 12 pin connector handle this GA? I suspect it needs to go direct to the ignition.
2. Do I still need the #2 connection from the Alternator to this +?
3. Do I still need the "R" connection from the starter solenoid to this +? I've read the original system uses this 'bypass wire' to get 12 volts during cranking so it shouldn't be needed for the HEI.

TACH just (Blk / Purple) from the 12 pin connector to negative, correct?

What are the connections on the HT starter? The positive must be the large center stud under the blue boot but which are the S and R? I only see one connector.

Which are the #1 and #2 studs on the alternator?

I'm not sure who wired this plug on the relay board since it is different from the V8 manual...
