Need help for 2019 Volvo VNL 860 Radio wiring - installation aftermarket headunit

Hello everyone
When I get my VNL it has factory sound system with sub and amplifier,
While accessories and ignition modes my radio player and clear amplifier was heating too much. After for a while, the radio units electronic card is gone. Previous owner installed so many cables and stuffs but he removed all devices and left a cable debris.
I get a Sony head unit and trying to install it. I search on internet and here but can’t find double 8 pins diagram.
I found this diagram at Volvo USA but can’t see double eight pins information
Here is diagram for sub and amplifier network

Also I’m not sure about connectors;

first one is double eight which includes power and speaker cables etc
I’m not sure about next (Yellow, blue and power) 3 connectors
Last 2 are antennas
Is anyone handle same process and Can Help me please?
It’s so boring being on the way without music
Thank you

 

From left to right
1- Iso connector (double 8)
2- yellow with one cable- What is this?
3- blue with two cable, what is this?
4- Black Power cable, For what?
5- antenna, For Sirius, I think
6- another antenna for what?
Could you please answer that questions? Is anybody know what they for?
Also, I need double eights diagram, The connector selling on the market cable is not matching because Volvo do not use the standard wiring. For example In US , black cable is For ground, but ####ing Volvo use green for ground what the ####! I watch many videos when people get a connector harness kit for double eight pins are not matching.

 

Thank you sir, but it’s not that easy because Volvo has a different wiring standard
