The only cable-activated locker I know of is OX. ARBs are similar in function but are air-activated and not much cheaper. Detroit Electracs are electically activated.
Ox vs. Aussie is apples vs. oranges.
there are 3 basic types of locker: Selectable, Auto-full-carrier-replacement and auto-lunchbox.
The selectable and carrier replacement require a gear setup for installation... this is a professional-only job according to most people and is generally pricey. The Lunchbox is easily installed by a home mechanic. The Ox is a selectable and the Aussie is a lunchbox.
HTH, sorry if it's redundant info.
