Fixed. I feel like a dolt. Careful as I was, I forgot to reconnect one of the electric leads to a microswitch that was hidden in the trim.

Thanks for the map. The codes from the diagnostic connector led me to the microswitch. The combination of your map, the 80 page booklet of diagnostic codes I downloaded from a member here, and the W124 CD service manual, helped me find the problem. It just goes to show that you can't have enough information for one of these cars.

The top now works perfectly.
