[QUOTE="LsGuy, post: 8734966, member: 681035"] To your battery, as it does from the factory. Then a new wire from your main battery (hooked to alt and used for starting) to this relay. Out the relay and to second battery. Then a 12v runs to a small post to energize the relay. What this does is uses 1 amp power from a 12v (that activates only while the vehicle is running) in order to close the contacts and make the circuit to the new battery. When the vehicle is off, contacts are broken and the second battery is isolated from the system. [/QUOTE]
