I've found a wiring diagram for the # DW08771 Battery Isolator. Terminal 1 would connect to the positive battery terminal of the main battery. The original wire from the alternator to the main battery would be removed from the battery and installed on terminal 1. Terminal E would connect to the an ignition circuit that's hot only when the key is switched on via a 6 amp breaker. Terminal A would connect to the battery lead on the alternator and Terminal 2 would connect to the positive terminal of the auxiliary battery.

I've provided you with a wiring diagram that's compatible with Ford-1998 and up.
