Air Conditioning Compressor & Accessories

Hello.

I have an air conditioning unit that I can't sell. It was originally installed in a Passat 35i. Now, I want to install it in my Golf 2 TDI with an 81 kW AFN engine. I need an installation guide or a diagram for this. Do I need a longer V-belt for the alternator and power steering? And where should I mount the A/C condenser, since the intercooler is already installed?
It would be great if someone could provide a drawing or diagram showing the complete structure of an air conditioning system.
Thank you for your efforts.
Olli.
