Power window problem / Fensterheber (3er BMW - E36 Forum)

Sorry to bother you guys with english, but can't seem to find any solution to my problem on any other forums. Have searched a little bit on this board and I did find quite a few threads...

The problem:
I bought 2x power window systems for my 92 sedan with door wiring harness and motors. But on the driver's door system the motor is equipped with an "ECU". It has a 6 pin contact. The passenger door has only a motor with 2 contacts and works perferctly. But I can't get the driver's door motor to run. The switch has a green socket with 4 small pins. How am I supposed to connect this to the motor and get it runnning?

The passenger's switch has a white socket and 4 thick pins. I sorted that out...

This is what I have done:

Brown/red from motor to +12v (ACC on ignition)
Brown from motor to ground
Red/white from motor to +12v Fuse 33
Violet from motor to nr 3 on switch
Black from motor to nr 4 on switch

+12v (ACC on ignition) to nr 5 on switch
ground to nr 6 on switch

There is light in the switch

So as it sounds, you have 2 different E-Motors, they have a different steering, one is controled by the power window switch, the other one get power from the ECU behind the glove-box.

One system run now?
The best is, you try to get for the other side the same E-Motor.

If you take a look on this wiring diagram,

Is it not possible to get the motor with ECU to work on my car?
Does anybody know which pin that should get which signal? I already know about brown for ground and red/white for fuse 33 on 12v. Then a red/brown, a violet and a black remains. From what I know, the red/brown should connect to the comfort relay (which I don't have), the violet and the black to my switch...
