2004 aero battery drain and CD changer

Have a problem with battery not lasting a week. Auto zone tested and battery and alternator pass their tests.
On-Star removed years ago.
Inspected vehicle with Flir C5 IR camera. There were two heat signatures. The device that reads the ignition key wirelessly showed minimal heat. That may have come awake when door opened. Did not put key in ignition switch.
The other the signature is from the CD changer and it was significant. It and the radio share fuse #9. So I cannot remove CD changer power that way. I never use the CD changer.
When I open the wagon hatch and expose the CD changer, ignition and radio off, when I slide the CD cassette acess door open, the CD changer motor driven cassette ejection occurs. So it appears that the CD CHANGER is always on, as the heat signature suggests.
The CD changer install looks like it is designed to prevent theft. So no easy access that I can see. So I cannot easy unplug it there. Is there a plug at the radio that would disconnect the CD changer from power? If I can get that done I will be able to see if that is the root cause of the battery drain.
The only thing aftermarket is a stage II performance ECU. (I have the original ECU as well.)
Thanks
