Adding an air pump for a ballast system

Hi all,
I am working with the 2.6 model for a research project for school. As part of the research we will be changing the weight of the payload. I am trying to install a Recirculating Air Bladder (RCAB) ballast system but am having difficulty figuring out how to hook up and code in the motor, any advice?
