Hello everyone,

So I need help with identifying the cables of the onboard monitor, I took out the onboard monitor with hopes of installing the aux cable I got from aliexpress, but I found no AUX connector and after some searching, on Google, I discovered that my e53 (2002) doesn't come with an aux connector behind the onboard monitor .

However, I found some weird cables coming out from the blue connector and one single blue cable which is separate from both white and blue connector and it seems to come from somewhere below the A/C controls... I have uploaded the pictures and marked the unknown cables with lines if you could help me that would be great.

And this is the lone blue cable that appears to be coming out from somewhere below the A/C controls:
