ALDL on 90 Coupe

The speakers on my 90 coupe are producing popping and volume variations when the ignition is on and while in operation. I need to find the ALDL plug to hook up a Tech 1 scan tool. Where is the ALDL plug???

I have done a search of posts, but did not find. The service manual gives three locations:

In passenger compartment.

Under ash tray.

Below IPC.

Help appreciated.
