Help Wiring Android Head Unit?

Hey I'm stuck on the wiring of an Android head unit I got off AliExpress and the company isn't being very helpful. Does anyone know the answer to this question?

* I have a 2011 Model II non-jbl.

The third one from the left (small 12 pronged) does not connect to any of the connectors in the harness they sent me.



The connector I received will only connect to 3 of the 4 so my setup would look like this:



I reached out to them and they said it should be fine like that, but I must be missing some functionality right?

Thanks in advance for your help!!

p.s. I have researched this quite a bit. I saw THIS thread, but it looks like his is connected. I also saw THIS thread where it sounds like that might be the case where I just leave it unconnected, but wouldn't some functionality be lost then? Sorry for the confusion, thank you for the help!
