Bear with me audio gurus...I'm a car stereo/electrical moron. I bought a new Shark II antenna. Is is amplified, but needs a source of power. Where in the hatch area can I find a wire that's always hot? The power antenna only gets power for like 30 seconds or so, so there must be some relay there. What's the easiest way to get power to my antenna? Please be descriptive with your answer..as I said...MORON here!! Thanks!!
