KST 1J0 959 799 Pinout: Connector Diagram & Info

Hi,
I have a problem: I want to connect my new 3BG rear hatch to my 3B car using the KSG (likely referring to a control unit or module), as it was originally designed.

I have reason to believe that this is possible based on the following statement:

"So, I would simply connect it the same way as it's originally done! Connect the button in the tailgate handle to the Central Locking System (CLS). The CLS then sends a signal that directly activates the actuator motor in the tailgate via a relay! This works with any 1J0 CLS, and I used the wiring diagram for a 1999 Bora Variant as a template, which also has the older CLS and electric tailgate. If you also do away with the unnecessary lock switch in the tailgate, you don't even need to run any cables through the car!"


Unfortunately, I am unable to reach the author.
Okay, so now to my question: Does anyone know which pin I need to connect the opening signal for the tailgate to, and which pin I need to use to activate the relay for the actuator motor? Or how everything else might be connected?
Please help. Thank you.
Best regards, Jaxx.

I found something.

THANK YOU VERY MUCH. You are simply the best!

Do you also think that I should connect the opening button on the tailgate handle to PIN21?

"And I can probably connect the relay for opening (not just unlocking) to pin 13, or will the tailgate pop open if I unlock the Passat with the remote control?"
Best regards, Jaxx.

So, if I understand you correctly, then what you're saying is correct!!!
