Opel Astra K - Upgrading steering wheel

Hi,

I have Astra K 2016 Sports Tourer and I’d like to change my steering wheel.
Beside original steering wheel is quite used and shabby, my main goal is to get heating option - my current steering wheel was lacking this feature, as you can see here:


I’ve seen on youtube and on some forums that people have managed to install Insignia B OPC steering wheel in Astra K, so I’ve bought one few days ago. It’s really great - leather is very nice and soft; driving with this is like another level of experience


But in order to get all buttons working I guess I have to change pins in connector. I get that arrows up/down won’t work because they are supposed to work with uplevel instrument cluster - I have midlevel, so they’re not important. However I’d like to activate heating button and music buttons - change songs and +/- volume and backlight would be nice   

Currently few buttons on the left side works (collision distance alert, cruise control button).

Do you have some pinout / wiring diagram for this connector? Maybe I have to do something else?

Thanks for all the help.

Well, after some struggles, I've found some schematics online, and I am afraid that my connector from - as GM calls it - Steering Wheel Air Bag Coil doesn't support heating at all. Probably only newer versions of Astra are able to work with heating, like this one: 

When you have this kind of steering wheel every connections supports heating systems - connectors in steering column as well as specific place in fusebox below a/c panel. 
In my configuration I have nowhere to connect heating module inside steering wheel.

These are my current thoughts about this.
Can someone confirm my theory?


So, to get functions from the steering wheel working, I swapped whole loom and switches from the old one to the new one. All controls works fine. Here:




Do you have any ideas how to set up heating?
