What's this part number?

[Robert Deis]

  447 035 225

It's a black electronics box I found under the left rear seat.  It's got
two plugs, but only one was connected, and most of the wires to that one
were cut and capped- as if somebody removed it from a circuit to prevent a
warning light or something..

What's it supposed to do?
