1987 300 TD (124.193) - looking for the location of the convenience control module (N57) that controls the power windows and sunroof.

On the W124 four door sedan, it is located under the left side of the rear bench seat.

Is it in the same location on the 124 wagon (estate)?

Can't seem to access the electrical component locator in the Electrical Troubleshooting Manual for this vehicle at STAR Tekinfo.
