Hello,

I was checking CD changer wiring and got puzzled.

it has 10-pin input/output.




Then it looks like Aux cable is coming out from the plug (red and white).




When I check the head unit, it has 20-pin plug.




It looks like that someone customised the wiring to extend it with AUX?

What would be the original wiring? Can I just remove the AUX (if this is custom built) and get new CD changer cable?

basically I want to bring it to the factory set up.
