What does the blue connection do?

Identified all the others but not sure what this blue one is for

If this is the amp I’m not sure how to connect that with my maestro and other harnesses

This is my harness. Nothing connects to the blue

Okay it must be this. I lost it in the sea of wiring somehow. But that still doesn’t connect this factory blue connection

Is it a coax cable? GPS antenna or something with rear entertainment maybe?

it is a sma connector so it is either gps or onstar, if it is onstar then you don't need it anyway

Okay perfect!

Now just to figure out the factory usb it seems I got the wrong adapter

 

[ls1frc]

Yeah shape is all wrong. It said a mini usb to usb would fit

I bought a adapter that fit for mine, but I believe you can just trim the plastic part off the factory connector and then it will work

I bought this one

It just looks like the metal shape is different
