Steering wheel audio controls malfunction

[Cartman]

Guys, after switching my steering wheel, my audion controls buttons on both site stops working.
Same day my car stereo and half of my dash was disconnected due to dash panel switch. Threrefore Im not sure where could be the problem.
Front buttons omn the steering wheel on left that controls dash and phone, and on the right that controls cruise control are just working fine.
I have triple check if I connected all wires to stereo, I have triple check if I have connect all wires in steering wheel.
I have measure all wires in steering wheels if there is some cuted cable, I measure audio controls buttons. All works according to multimeter.
I checked also part numbers on the buttons and they do not Match the Mopars but before changing steering wheel they works fine.
I cant find any scheme how are the steering wheels buttons thruout steering wheel ring connected to car. stereo.
Would be anybody so kind and help me with your advices, or schemes or experiences?

Today I removed the radio. There are quite a few connectors at the back. One mini USB B-gray, three Fakra connectors that don't match the colors, and one large connector. In my opinion, there is no way I would have connected something wrong there. The Fakra connectors don't match the colors. I have white, yellow and red on the radio. The blue cable goes to the yellow connector on the radio. There is also an input for a black mini USB B on the radio, which is not connected, but it is not connected. The black mini USB B goes from the center console to the car socket. I don't know why the black mini USB B doesn't go to the radio. But I'm 99% sure that I couldn't connect something when I turned on the radio and cause the buttons on the steering wheel to not work. So I still don't know why they stopped working.

ok I found maby something... but who can help me read it?

help me if I'm reading this diagram correctly.
It has a left and right switch.
From the right pin 1 and from the left pin 1 it should go to pin 9 of the connector.
but from the left pin 1 it should go to pin 1 and from the right pin 2 it should go to pin 2. and in my case I measured both on pin 2 so the error should be in the wiring. There will be a broken and shorted cable somewhere.
Am I reading this correctly?

So I took the cables out, stripped them and checked them. Everything looks fine, I insulated them again and I'm back where I was, the buttons still don't work.

You can check these wires with a multimeter.

This is the diagram and connectors for the radio control.

When I had it disassembled, I measured everything.
So to be precise, I measured the continuity of the cables, whether there is a signal between the pins in the connectors. I measured the continuity between 1 and 2 and 9 on the left and right connectors 1 and 2.
I also "dissected" the insulation and visually checked the cables. I also moved them, whether they are torn or broken inside.
Currently I think that the fault will be in the ring under the steering wheel. because the switches are ok, the cables look ok, so I'm going to move on. I don't have another steering wheel with switches and wiring to test.
Thanks for the materials and hints Zeep.
I will buy a new harnes for connecting the rear window - the wiper and washer on the rear window. The harnes includes the right and switches. So we'll see.
The only thing that surprised me is that the buttons on the steering wheel are supposed to be backlit? Because mine are not.
