'93 500E Battery Drain, Fuse #9, Symptoms Listed

[ashyers]

The 500E has developed a problem recently and I'm having a tough time sorting it out. I have a battery drain that's taking place through the following lamps with the key removed:
E20 Exterior Lamp Switch Illumination
E10/2 Left Air Outlet Illumination
E12 Trans Selector Illumination
E10/3 Right Air Outlet Illumination
? Rear Head Rest Illumination
? Rear Sunshade Illumination
? Left Seat Memory Illumination

In addition the Radio functions w/o the key in the ignition.

If Fuse #9 is removed the draw on the battery stops.

I'm hoping that someone has had this problem in the past and can point me in the right direction. I have tried disconnecting the CD player, Power Antenna, Audio Amplifier, and Door/Hood/Trunk Switches, but this has had no effect on the draw. Any ideas here? I'm gradually pulling the car apart chasing this thing and can't say that I enjoy pasting wiring diagrams together from 8 1/2 x 11 print outs! Thanks in advance for any help !
