The car was an 89 300E with a leather interior in great condition. I wanted the seats and was determined to get them.
After studying the power/memory seat schematic I did the following:

1) I hooked up my B&D cordless drill 14.4V battery pack to the fuse block and the body. All the fuses has been taken from the fuse block. Positive terminal went to the tab for fuse E or F (can't remember which - one is for driver seat and the other is for passenger side) and the negative went to the brake master cylinder.
2) With the driver's power/memory seat switch removed (someone had already taken it) I opened the connector body(s) to expose the wire terminals.
3) Then it was a simple matter to touch the appropriate wire to *ground* to get the seat to move the way I wanted it to. Touch violet to ground and the seat moves forward. Touch blue to ground and the seat moves rearward. Ground white and the front of the seat rises, black and the front of the seat drops. And so on using the colors I posted above. I didn't mess with the headrest or recliner functions but they undoubtedly work the same way.
Very satisfying to see that seat come to life in the junkyard.
The real difficulty was unplugging the wiring harness connectors from the memory module on the seat adjuster. That 16-pin connector is hard to access and very, very tight.
