Breakaway Cable on Andersen Hitch.

For those of you that use the Andersen Ultimate Hitch, how do you hook up the Breakaway Cable? I thought, about putting it over the Ball on the Hitch, then hooking up the Coupler on top of it. Then I thought, it might prevent me from disengaging the Coupler from the Hitch when I want to disconnect. How do others do it?
