because thats the way they choose to do it. Besides, if everything was running when you tried to start the vehicle it most likley wouldn't start due to excess voltage drop, thats why the acc. is turned off during crank

Ok, why does acc have anything to do with ignition wires(whether there is one or three ign wires they all stay on when cranking, that is why they are called ignition instead of accessory)? There are multiple ignition wires to isolate circuits, and to provide power to different computers in a vehicle.

This question was meant for someone who might have insider info.
Anyway I like the second answer. "because thats the way they choose to do it".
The "acc" wire was never brought into question. That wires operation does make sense.
