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

If someone has worked on this before please shed some light to my question. 
TIA
