I run ARB's front and rear. They run off an air compressor mounted high in the engine bay. You can use either a blue plastic line or a steel line that plugs into the axle housing. Then I have 3 switches mounted in the jeep, one for the compessor and two for the lockers. The cable lockers such as OX lockers have gotten better, I recall some ealry one's that had engaugement issues. Think parking brake line, as you use it it tends to slip a bit, thus the ox line would slip and not allow for full mesh of the parts.
One other item to keep in mind, if you have the dana 35 rear, a locker back there is going to put a lot of stress on that axle. It tends to blow up when that happens, You many wish to upgrade your axle shafts to help with this.
