Thanks Jason. I'm mostly interested to see if the thing turns on when I connect power to it, but, am unsure which of the 3-prongs in the back is for power. I believe, as you look at the back of the radio, that the power "prong" is the one to the far right, (the other two have a different wiring connection...), however, when I grounded the housing to my 2008 Honda and then connected power to that prong ...it sparked like a sunofagun. I hope I didn't cook the radio - seems like there's a bad connection somewhere, and I didn't see the radio's light come on... It kinda sucks to know enough to be dangerous. This is dangerous!!! Jay
