Does the stock neutral position wire prevent the car from starting unless it is in neutral? What exactly does the stock system use it for? Will a WRX start in gear with the clutch in? Most likely it will - I don't know since I'm still waiting to get a 04 wrx. Thanks!
It seems to use the neutral wire for regulating cold start idle engine speed. If you notice, when you put it in gear in the morning, the RPM's drop. And no, it doesn't prevent it from starting in gear. The clutch does that; that's why you have to trick the car into thinking the clutch is disengaged.
