I have a 2002 caravan se with the am/fm/cassette. I have a chance to buy a 2003 factory am/fm/cd to replace the radio I have. I understand the 2002 caravan radio might have what is reffered to as the old factory radio plugs,2 of them. That chrysler made a change to a new style plug (1) I was wondering if anyone knows for sure what plug was used on the 2002 se
