Climatronic G3 TDI

Hello, I want to install a Climatronic system in my G3 TDI. After studying the plans, I have a question. Can someone tell me where all the vacuum lines need to be connected? Specifically, I'm referring to the supply unit with the reservoir and the two-way valve. Everything is already connected on the control panel itself.
'I'm missing the vacuum supply unit... So, if anyone can sell me one, I would be very happy!'
Best regards, Tom.

HI,
Which vacuum supply unit are you referring to?
The vacuum line is connected to the vacuum pump using a T-fitting. Additionally, there is a check valve in the line to prevent the vacuum reservoir from being emptied when the engine is turned off.
Is that enough?
Best regards, Benno.
