Need some help connecting to Bosch Easy Series

Hi all,

I need some help setting up my just received konnected system on a Bosch Easy Series. This is the set-up I'm trying to have:

Some pictures of my system:

I'm very new in all of this (I did not do the original installation myself) so I've some questions:

1. I do not immediately find where to put the 12v AUX wires since I do not have this indication on my system, where should I put it?
2. There are two outputs for each zone on my panel, where should I plug them?
3. Where to connect the relay?
4. Can I avoid using the external adapter?
