[QUOTE="Wallijig, post: 272199, member: 6398"] I believe it's just fused up under hood. I have hooked into that wire for topper lights and aux power in toppers. One should add a battery isolator or dual output alternator for charging. Without one of those one would be in parallel with truck battery. You can get them at a high end car audio dealer. I have installed both. I liked putting in dual output alternator better. Just look in alternator application book for vehicle you have and order replacement. Unbolt and rebolt back in hookuping using same factory plugs. then just have separate post on it for charging aux batteries isolated from truck electrical system. [/QUOTE]
