I am running a stock alternator. With the Ford Fuel Injection harness it says that the purple goes to "start" and red goes to "positive." I am correct in assuming that "B" would be start? I didn't see any S or I's.
A(big connector) = Positive
B (small connector) = start signal
C (small connector) = ignition (+12V when key is turned to start AND run)
D (big connector) = Power that goes to starter when start signal received.
You are correct that B = start.
Sorry I can't help you with the alternator wiring, I switched to a single wire alternator years ago.

B- is the start term.
red will go to batt side A.
The efi gets it pos to coil while cranking from a differant signal wire.
which would post C be attached to with stock system.
