there are some
Older type for 5 gear auto ML-320 and e320
with different shift pattern
And similar to ours for S Class with additional switch for winter/summer
Newer 2005+ Benz cars have 7-speed.
It's described as genuine Mercedes unit.
I don't know about mechanical fitments issues, donor module is definitely needed.
Although it looks like quite similar we can not change just printed card board with electronics because of different shift pattern.
As far as shift pattern is concerned (it's D-4-3-2-1) it may be differences in CAN bus PIDs also, so new matching TCM may be required (however I'm not sure)
If all above is solved, don't see big problems in rewiring SLA electric socket, even if Mercedes unit has rear gear switch inside SLA, we won't use it, all we need are "can bus +", "can bus -" , +12 V, ground and may be illumination.
As far as I know in Europe Mercedes incorporate anti-theft features in SLA unit, shift from Park is not allowed, if immobilizer unit didn't recognize valid key (even if the key mechanically fits (cut)).
