@ZimaSpartan did you already buy the Multicontrol? If not, go and get it and you will receive the installation manual in the package.
Anyway, here's the answer:
From your photos, it seems T6 and T6.1 both use Thermo Top Evo. The red connector on your photo also has a green-white wire (pin 1).
So you should be good to go with Multicontrol.
The pinout from multicontrol connector is described
here on page 15. Basically, you need to connect yellow wire (pin 1 square connector) to green-white wire (pin 1) on red connector under the seat.
Besides this you will need power and ground. For ground there is a bolt under the seat where all wires come out. For power - tap into existing connection under the seat (and put a fuse inbetween!).
I suspect just like with Telestart coding will be required to get the aircon to switch on. Engine should warm up without coding. Anyone knows?
Post here once you get it done. It should be a straightforward install.
