The best ground connection inside the engine bay is under your windshield washer water resevore. Remove the black plastic knot on top of the water resevore and pull the resevore up and underneath you'll see a screw welded to the body and a bunch of brown wired attached to it via a knot, remove the knot put the ground wire between two of those wires and then tighten it back and that your ground. For the positive which is direct connect to your battery, there is a jumper terminal on your driver side front shock tower, it's a black plastic box, remove the cover on that small box and there are two wires inside that box they are both positive direct lines to the battery, either one you connect it to your ok they are both positive. Hope this helps.
