You probaly have the Roadmaster Brakemaster mod 9100 without the breakaway kit ! Click on the instructions on the 9100 or 9160 to see how to hook up and what you are missing, the breakaway is a good audition to the 9100 but a little expensive for what you get. You can build one by buying a Mac valve model 35A-AAA-DDBA-1BA at about $30 and a small tank and a few brass ftg.
