2004 f250 usb
 

I want to add usb ports in the back seat area there are no cigarette lighter ports any idea where I can draw power? I was thinking from the back window motor but don't want to mess anything up. Any advise is appreciated thanks

I remember reading somewhere that there is power inside the back pillar on the right or left of the back window. If it's not hard to pull the trim off I'd look for a free connector in there and test it for power when the key is on.
