Window regulator needed.

[m0rda]

Yes, I understand it is - all the circuitry for the rear windows is missing. Only things I had, were the console buttons, which were just hanging in the air. Judging by that, I thought that rear windows were electric, but they were actually not. My mistake
At the moment, I have all the buttons, relays and rear-left winder.
The most interesting will be to find points "9/B4", "9/B1" and "13/A2", to which the relay 810 and backlight connect to.

I should have a spare harness somewhere i stripped a v6 sei and a 2.1 sed both with rear power windows.

Finding the harness or at least identifying it is another thing.

The only hint I might have is that there should be these 5-pin connectors:

These are connectors to door buttons.

Yea they are the door ones.. the centre console ones are the same as the dash switches ...

Are S1 and S2 harnesses the same?

I've not checked, but iirc, the relay plugs into the main fues/relay board and the connections are from that board and behind the radio, as said by citroenxm.

Buttons are the same, for sure. The difference might be in motor connectors, as S2 and S1 motors are different.
However, I haven't had a chance to compare, as was an owner of S1 or S2, but not both at the same time.
I would say, for my purpose, S1 harnesses would do, as I only don't have console button connectors.
