I bought this vehicle with a bad radio. When I went to install new one I touched the red wire to metal, I am sure I blew a fuse. With the new radio it only works with the key in the on position and you have to reset every time you restart. I have pulled every fuse under the dash and under the hood and replaced, still cannot find the bad one. If you have any answers please help. I know it should be the acc fuse but cannot locate.

There is no red wire in the dash. Could that be a pink wire? If it is not, it is not original and someone else left some other radio's harness in there to confuse us.

The pink is the memory wire and is tied to some other circuit that is always live. Chrysler has always used the interior lights fuse for that. It should be listed as "dome light" fuse, and is a 10-amp. Check for twelve volts on both sides of that fuse. There are two tiny holes on top for test points. Or just observe if the dome light works. If it does, that fuse is okay. If you have zero volts on both sides, work back to fuse F14 in the power distribution center under the hood. To speed things up, if the horn works, fuse F14 is okay.
