Ballast question...

[TL7]

Can the old style sacs be plumbed for auto ballast? We have the 07 Outback that has the stock fly high sac in the back (350lb I think). I have one of the old Launch sacs that is 680 lbs. Can I use it with the lines that are already run? If so, what kind of connections do I need? Or would I be better off just buying the Fly High Pro X 750? Link is to a pic is of the old style Launch I have.
