I bought a nice '98 Grand Marquis a few weeks ago, low mileage and super shape. It has an AM/FM/Cassette deck that has a CD selector and the controls. I am sure it is supposed to be able to interface with a factory CD changer, which the car does not have.<br /><br />I have pulled the radio unit out to look at it, and there are no empty connectors on the back of it. There are three connectors back there. I have pulled the trunk apart, looking for the end of a cable that I believe should plug right in to a factory CD changer, which I plan to get off Ebay. But I can find no such cable. I've even looked under the back seat.<br /><br />Does anyone know where that cable might be hidden? Can anyone tell me where the factory CD changer would mount in the trunk on a '98? I'm not getting much help on the sites that specialize in car audio...everyone there seems to be obssessed with earsplitting power and subwoofers that cause earthquakes. I just wanna play a CD in my car now and then, I'm not trying to impose my musical tastes (which are quite sophisticated, if I say so myself) on anyone else!<br /><br />-dd-
