Restoring Mercedes W124 CE300 Coupe: How to Master Belt Feeders & Troubleshoot Control Issues

Hello, I am resuscitating such a Mercedes. I cannot master the feeders.
I open the car, open the door (I checked the limit switches, upper mass,
middle +, lower mass, pressing the middle one snaps a relay in the board.
mass comes to the module) I make a jumper on the ankle from the armchair, close the door,
I turn on the ignition. And the feeder just vibrates. Motors working, I checked on
short. When I disassemble the module and short circuit, the relay comes out, pressing the other retracts
out.

My guess is the control is missing.
I do not know which pin to give the mass and when it should turn on.

in the module cube there is a constant mass, a constant plus and plus after ignition.
I need a diagram of how to connect this module.
I had one found somewhere on the internet supposedly from 124 but unfortunately it didn't match.

Hello gentlemen. I dealt with this topic, it was enough to adjust the limit switches on the rail. However, before I got to that, I went over the installation.
Please, here is a diagram of how it is connected ON THE PASSENGER SIDE.
Maybe someday it will be useful to someone.
On the second one, I didn't have to research, so the colors may be different
