Connecting Vertex Central Locking and Switchboard in VW Golf 3: Tailgate Actuator Issue

Hello.
I install Vertex central locking and switchboard in VW Golf 3. I replace pneumatic locks with electric ones.
Everything is nice, but there is a problem with the actuator that opens the tailgate, namely, I would like to use the channel that is responsible for opening the tailgate with a plus. The actuator opens as it should, but I would like this actuator to close at once. And my point here is that he only unlocks the lock so that it can be opened. I used the relay, but I don't know how to do this, and here's my question, how to do it? Do there have to be 2 relays and how to connect them? Can it be done on one? And I will add that the actuators are controlled by "mass" because "plus" did not want to work. Here is my connection diagram:

Thank you in advance and best regards.

From what you wrote, it appears that you need the boot actuator to act like a servant, that is, you have this output from the output to control the rear door. You open the car, everything opens up and when you close it all closes. No additional relays

Well, I just wanted to do as it is, for example, in buses You have 3 buttons on the remote control: Open, Close and Paka. You click "Open" opens the front for you (the crate is closed), you click "Paka" it opens only the back and when you click close it closes all

By "signal" you mean the mass that appears on the black and white cable when closed? Is there a plus on the white cable?

I connected it as you drew and the additional actuator works, it opens after holding the 2nd channel of the button and closes after pressing the "close" button but the other actuators open correctly but do not close and the "Master" actuator does not respond to manual opening and closing. I will only add (I do not know if it matters) that the white and black and white cables from the control unit do not run to the other actuators, only to the central locking console, from which they divide into 4 actuators (2x Master, 2x Slave).

I connected the 2 way and it works. This is exactly what I meant. This switchboard works a bit stupid because it has locating the car and when I open the trunk or open the car with the key, the switch still thinks that the car is locked and shines with directions for locating and when I want to close it with the remote control, I have to open it first and then close it, but it is difficult Thanks a lot for your help
