Well done. Always nice to see lots of pictures. I did this job last year. Not a bad job but long, kinda like pulling the dash. The red plug should engage the airbag socket with a clearly audible "snap" according to FSM (mine did). Make sure the key is in your pocket and the battery disconnected before playing with the airbag, "just in case."

SJH, I thought the adjustable steering wheel was standard in all US-bound 124s. My car has the adjustable steering wheel, memory seat, etc., with MB-Tex seats but without heated or orthopedic seats. The adjustable headlights were a Euro-only option, DOT never approved them (or Mercedes didn't ask) but they can be retrofitted -- I am doing that installation now, as it turns out.

It may be possible to remove a complete adjustable steering column from a donor car and transplant it to yours; the steering wheel position is stored in the seat position memory, BTW. If you don't have a driver's seat memory some wiring changes would be necessary.
