That's a good question - I have the cassette player with the 6 CD changer (in the trunk). I think they also offered a CD player in dash with the 6 CD changer option (i.e., what jason01cougar is trying to recreate) ... Common sense would suggest the connections will be the same, but this is Ford we're dealing with.
Anyone know the answer? If the connections are the same, is anyone willing (who isn't using their factory CD head unit) to swap for a cassette head unit?
