NOTE:
YOU CAN put it as: ActivateSignal(OutPut3) I guess that must have changed, Brian might have changed it. It used to be that the Signals where ALL in caps (see wiki still up like that). But Hood pointed out that he has been doing it like the above, so I tried it and sure enough it does work that way........... so, I stand corrected, I was unaware that it had changed............
