i cant find an acc power wire from the original stereo wiring harness (when ignition is turned on) for the stereo so it automatically fires up when i put the ignition on... is there supposed to be one, or do i have to share a wire that goes to the AC control panel..?

I think there is no wire for it there, at least i didn't find one. So i ran a wire from the rear window blind button, just above radio. It turns on when you turn the key to "all power on".
