'12 Enzo SV211 Ballast Help? Not sure whats stock vs aftermarket

[dasredsox 0]

Just bought a used '12 Enzo SV211 and need help figuring out my ballast system. Any '12-'13 Enzo SV211 owners out there that can help me identify how the ballast is supposed to be set up? I cant tell if I have aftermarket bags or what is stock and supposed to be working with my provision II dash. I have PNP bags in the rear lockers but they are plugged and disconnected from anything on the boat. There are two water hoses that are just loose without any fittings on them on the starboard rear side that would have reached the bag but there are no fittings (have band clamp impressions though so were connected at some point). Are the locker bags stock or is this aftermarket? Also the dash screen seems to "monitor" the fill level on 4 bags/tanks (rear tanks and mid bags) but there are 7 in total- 2 rear built in rear tanks, 2 rear locker PNP bags, 2 mid bags, and a bow bag. Lastly, the dash seems to report the rear quick fill tank fill level based on the time that the fill switch is engaged on open as opposed to how much water is in there because if I open the gates  using the fill switch while on the trailer it will show them filling and then emptying when I engage the empty side of the switch even though no water is going in or out. Effectively making it useless for monitoring the actual fill level, Is that how its supposed to work? 

Any help from other people who are familiar with the system in my boat is greatly appreciated. Im a first time wake boat owner and am already getting overwhelmed with the dark side of owning one 24 hours in...
