E34 M5 memory power seats into E34 520i

[KevinK]

Hi, the previous owner of my 520i installed black leather interior from a M5 1994.
As you might know, the passenger seat does not have a memory function and is easy to bypass, but the drivers seat he could'nt figure out.

I cant figure it out either, I understand that I have to split the original connector from my 520i, but I have no idea what has to go where.
I don't care if the memory function don't work, all I need is the adjustment to be functional.

I read that you can ground a wire to bypass the memory function, but I have given up.
Here are pictures of the connectors:

The one from the cars original harness:

This connector is just the same as mine, only I have one extra blue/white wire I think is for the background light.

The ones on the seat:

I have figured out that the small connector is for the heat.


Appriciate all suggestions, thanks !

I read in another board that you need the wiring loom from the car that had the memory seat. It then plugs somewhere under the carpet of your car. You need to get the woring diagrams i order to splice the wires correctly.
Good Luck!
