Vikki;
With the batt fully charged I had 12.68V across the posts with same from Pos to cyl. head bolt.

Next I examined the starter cable from batt to starter including bolts etc. All good and insulation as well. The neg. cable is appears new and is without damage.

Headlights not terminated as mentioned.

Shifter - in park and thru each position to test neutral safety switch (no change).
Note: Column position also tested with every combination possible between the shifter and column less the Divinci Code!

Ring gear....not visible because of headers. Perhaps to be checked when transported to shop for quarter work.

Heater blower mtr no response (if it is even connected. The individual disconnected the heater hoses so...)
The S terminal you spoke of is it the one that has a red wire that goes from the solenoid back up to the engine bay harness and bulkhead?

And lastly no console with purple wires as you had mentioned.

Owe but I could sit in it and light a smoke! the lighter works as do the wipers. But I do not smoke and it's not raining at the moment.

I remeber years ago you could lay a screw driver across the solenoid to at least have the engine crank. Would this cause more harm or is it worth a shot?
