What I do on all my installs is I get the Chrysler wiring harness and a dash kit from somewhere like Best buy. That way there is no cutting of the wires and the dash is not altered. So if needed you can just plug in the original radio. I have done this to all my cars because the factory radio sucks. Even the Chrysler C/D radios that I have put in sucked as well. The audio controls for both units lack good quality sound. Put yourself a good Pioneer, Alpine, or Kenwood unit in and you will see it is night and day!
