Campell Breakout Board Hook up

I am an electronics idiot. I need a little help clearing this up
before I hook up power. I have dan mauch control box, and I will
explain how the power comes in. Ok, coming from my power cable from
the wall to the control box, I have a ground, hot and neutral. The
hot goes to the front lighted switch top post, neutral goes to the
bottom post. The middle post on the front switch goes to the
transformers. I am assuming I run a wire from the middle post that
goes to the transformers to the hot connection on the campbell
breakout board, but where does the neutral come from, should I just
take a wire from the bottom post on the lighted switch and hook it up
to neutral? Thanks again.
