400W/12V = 33.33 A. You probably want a little margin so maybe 35 - 40 A; there should be a sticker or note in the owner's manual (if you lost it maybe there's one online?).

and you probably want to use 10 gauge wire.

Everything I say here is my opinion. It is not my employers opinion, it is not my wife's opinion, it is not my neighbors opinion, it is My Opinion.
