Ya I couldn't think of anything definitive. Either your cig light is on, you'd probably notice if the lighter itself was drawing power. The radio perhaps? You'd probably notice if that stayed on. It's a refurbished stock unit? So probably no memory wire, just the power wire. Guess you'd just have to bust out the multimeter and see what's drawing. Didn't leave your lights on while you were playing with with your new stuff did you? Esp if the cig light was wired into the dash lights and you were playing with it at night. Or the guy wired it straight to power, and it's always on, and you didn't notice it never turning off if it was daytime?
