Golf IV BX30: Central Locking Control Assembly Connection Issue - Opening/Closing Signals

Hello, I have a problem with connecting the central locking controller. In the door I found the positive (it was almost 12v) cables from closing / opening, I cut them a bit and soldered the two-wire cables and led me inside the car. I soldered the white and white cable with the black stripe to the cables previously routed to the car (white cable - opening signal, white with the black stripe - closing). Yellow and yellow cable with black stripe connected to the ground (car bodies). The problem is that the car can close or open today, for example, with a stronger "slam" the door closed (closing and opening the remote control works correctly). Could it be the fault of hooking up to the body instead of the downside of the installation?
Below I give a diagram for this driver

There is weight control not a plus so I don't know where you got the plus cables.
We connect to the yellow-blue - closing (white from your central unit, you use the scheme C), green-red - opening (white and black). These wires are in a bundle in the middle of the door, they go from the lock to the controller in the door. 0.75mm2 cross section.
The weight is on the car body, so it doesn't matter if you take it from the negative pole of the battery or from the car body - it is only important that there should be a reliable connection to the metal sheet.

In my door there were yellow wires with a blue stripe, yellow with a green stripe and blue with a yellow stripe and green with a yellow stripe of cables that were responsible for opening / closing I was looking for by gently shorting the cables in order one after the other and after conclusion of yellow-blue and yellow - green worked. After turning the key the voltage from 12v disappears for a moment to 0 and returns. I think otherwise there is no option to connect because after conclusion of the rest of the cables, there were no effects. So if I think solid mass and white and black and white sends a signal to these wires?

In another diagram, the colors of your wires match.
Disconnect the plug from the lock and see if this happens again. If not, the lock is damaged. If it goes on then the lock is ok and maybe your wires are somewhere worn through the grommet because you had to add them there or something in the new drivers is wrong.
You can disconnect its plug for testing.

Well, just a very strange situation with this because the cables are securely secured so that they do not close anywhere, I will try to disconnect the switchboard and check for a while if it is done.

Added after 26 [minutes]:

EDIT: when it opens / closes itself, the directions do not flash as it gives from the remote control, it flashes so it is rather not the fault of the control panel itself.

good remote control unit disconnected and see what happens somewhere must be short circuit

This only happens with the driver's door?
What happens if you disconnect the driver lock plug?
In my opinion, the problem lies in the driver's lock.

Only with the driver's door and only opening inside from outside can you open normally and nothing happens as if the inner door handle was doing a short circuit somewhere. Tomorrow I will unplug the plug from the lock and we will see but somewhere short circuit is not another option.

Damaged lock or tie between the handle and the lock rubbing through the wires. If you unplug the lock and it will be the same, look for worn wires.

Gentlemen, "expert help" is needed in the assembly of the BLOKER (Stiga) switchboard. Car: Golf 4, 1999, 1,6, there is a factory central locking with the windows closed after holding the key in the closed position. The problem appeared at the beginning, when looking for wires supplying a closing and opening signal. I undressed the harness on the driver's door and started checking with the door closed all in turn with the help of a tester (mass to the bolt securing the jack plate) by touching the isolated wires. From the analysis of earlier statements about the assembly of the switchboard, it appeared that the two wires should give the lock a reaction (close or open). Unfortunately, nothing like that happened and a few wires showed voltage. Using a video on Youtube, I searched for two wires coming out of the connector socket at the windscreen motor (pins number 4 and 24 - cables of green-red and probably yellow-blue). They are said to be responsible for signals in Golfs. They go to the lock, but the voltage is on them all the time (!) And disappears for a fraction of a second when closing and opening the door with the key (on other wires with voltage this reaction is not present). Hence, I conclude that these are the right wires - but why is there electricity on them?
I will add that I connected the switchboard so quickly (ground control - battery power, weight from under the bolt securing the lift plate) - the switchboard works (you can hear distinct bumping) and there is a strange reaction to opening but only "sound" and not always. When connected to the "control plus" nothing happens.
Did anyone meet with something like that once? Where could the problem lie? I will be grateful for every word of sensible advice ....
I will add that the central locking with the key works well (except for the tailgate, but there may be another problem).
