What is silver box under dash?

I have an 87 911. Underneath the radio, under the dash is a silver box about 5" by 5" by 1" that has a black plastic end and wires running into it. It has a Porsche part number on it, so I do not think it is aftermarket. Any idea what this thing does?

My brain is in the front compartment, are '87's different?

Does it cause any effect taking it out other than no cruise?

Make sure it is the brain, mine is in the trunk, not under the radio.

I think that they moved it under the radio in '86.

Yep. Cruise Brain. Just to the right of the ash tray under the radio. Don't toss it. A working cruise brain is worth a few hundred bucks.
