CD changer on X300?

[TWINTURBODAVE]

Hi all...Having just bought a bargain '95 3.2 XJ6 without a CD changer ( but with a CD button on the stereo) I wonder if I can easily attach a CD changer to it...I happen to have an Alpine changer ( which coincidentally is the brand Jaguar used then) complete with the wiring....I wondered if there was a simple plug in socket somewhere on the car?....any help much appreciated...
