Ok so i goofed when i swapped out the factory CD player on my 2003 ram when i left a cd inside the unit. Can i power it up off of a battery just to get it out? I would guess that 2 of the pins could be hooked to a battery just to get some juice to it. Does anyone know which 2 to use?

 

Looking at a wiring diagram, appears Pin 1 and 12 is positive. 11 and 22 are grounds. Just pick one of each and try it. Looking at rear of radio though, not sure if they are numbered or not, don't have one to look at.
