After some testing I was able to put the Yaesu rotor G-1000DXC working. It took me some time becase the documentation is not really well explained.

Connector

The connector is a 6 pin connector. I tried to buy it in aliexpress but I couldnt find it, so I designed my connector in solidworks. You can download it from here. You need to crimp the connectors, it took me some time until I learn how to do it without breaking them.

Connection

The connection of this connector took me a lot a lot of time. I am going to explain here how did I do it.

And the cable that is connecter into the rotor has the marks with the numbers. A photo of the numbers, from the point of view of the connection (not the soldering part):
