On my Avy it was plug n play. I just removed the hard tanks and attached the in/out/overflow to my Avy sacs. I dont have a write-up. But if you post on centurioncrew.com, I am sure that somebody does.
Edit: this may be useful. Go down about 1/2 way and Bigshow provides a quick write-up and pictures.
