I was building my new Crack kit that I just received and it says to solder the "line" wire to transformer pin 1, and the "neutral" wire to transformer pin 2. However on the transformer itself it says pin 1 is "0v" and pin 2 is "120v", which seems to be labelled oposite of how the manual says to wire things. Is the manual's wiring correct or should I be following how the transformer is labeled?
