Aquahub Pumpstopper Kit Install

[aqure591]

Hey fellow reefers. I wanted to know if anyone has worked with the aqua hub pumpstopper kit. I placed an order got my shipment of the unit and was confused with how to install it.

In particular I'm confused as to what I do with the 12v Wall transformer. Here are the instructions for the DIY http://www.aquahub.com/store/media/P...struxMar11.pdf
If someone has worked on this before please shed some light to my question.

TIA
