The circuit uses the Neutral Safety and grounds Pin #30 through the Starter Solenoid.
So it uses the Starter Solenoid even when the engine is running so yes it could kill your engine when you put it in gear with this wire not hooked up to the starter solenoid.

So with the NDS wire (pin 30) open or disconnected the idle would be higher in neutral but would be normal in gear so this is not your stalling problem.

Thanks for the diagrams. I'd been wishing I had photocopied the ones I had ever since I gave the book back. I figured out the ShopKey wiring diagram too. They tried putting 5.0/5.8 and AOD/E4OD all in one diagram making it very confusing.
You're right, it won't affect the stalling. I hooked it up to the S terminal today and ran it then checked codes.
KOER:
25 KS not sensed (I don't recall seeing a knock sensor on this engine)
52 PSPS open
KOEO:
52 PSPS open
Continuous:
29 VSS (not hooked up yet)
I can jumper the PSPS connector to get rid of that code, correct? As for the stalling problem, I found it only does it cold. I should check more thoroughly for vacuum leaks. I didn't find any obvious ones and when I unplug the IAC it dies. Any other ideas?

ECT (Engine Coolant Temperature sensor) the one with two wires on it.
ACT (Air Charge Temperature sensor)
TP (Throttle Position Sensor)
