My custom car charger when finished will help many people well at least give the idea on how to do this yourself this will possibly be fabricated if it works perfectlly. I am not sure if something like this is invented. if there is can someone tell me the name or a link to it. if not my question here is what wires are responsible for charging the ipod on just a charging cable there are only 4 wires inside it. If anyone knows about 17 core ipod cables/ 30 pin ipod cables please post info on them anything helps. something kinda like this but with a female ipod jack were the headphone/aux jack is and a 17 core cable.
