Sorry, I couldn't see the photo properly.
The problem is here; you don't need to add any channels. You need to change those pins. I had the same problem. Change them and let me know how it goes.
I've attached photos of my connectors, before and after.
You still need to add the ceiling speakers, just like I did. My covers are due to arrive, and I'll install them then.
