A ground wire to the chassis and a wire from the + battery post. It isn't a good idea to charge it this way without an isolator because the voltage regulato/alternator will not charge both batteries with the the same voltage/current. It could damage the alternator if used for an extended amount of time.

Suggested Repair
Do not charge a spare battery by running only a chassis ground and a positive wire from the main battery without a battery isolator. The alternator and voltage regulator will not properly charge both batteries at the same voltage and current, and extended use can damage the alternator. Use a battery isolator if charging a second battery while driving.
Conversation Summary
A Nissan owner asked which wires are needed to charge a portable spare battery while driving so it can power lights and music while camping. The expert said a chassis ground and a positive wire from the battery post would connect it, but advised against charging this way without an isolator because the alternator will not charge both batteries correctly and could be damaged if used for a long time.
