I was just shown the tip listed above about the test light. Works like a charm. If the light does light up, you can begin to pull fuses, as soon as you pull the fuse linked to the "problem" the test light will go out. However you must also keep doors closed or keep the dome light pin switches pushed in as they will cause an open circuit.
I actually was able to track my "draw" to the tail lights, one of them was not grounding out properly, as soon as I wiggled the socket the test light went out...
