Year of subject vehicle?

Get a hold of a wiring diagram for it or have the dealership print you out the exploded view from the parts book so you'll have an idea where it all goes.

I'm not familiar with that vehicle, but it all depends on what you want to accomplish. If you want to keep the same 12V system, but double the capacity then you put them in parallel. If you want to move up to a 24V system, and keep the same capacity then you put them in series, just like a flashlight, or radio.
