I need help on how to do a quick install.

I bought a aftermarket stereo for my car. Pioneer touchscreen.

I lost ability to use stock usb and aux output in the center console.

I purchased "axxess toyusb" adaptor to be able To gain back back usage of then usb output.


I understand that the usb part of the adaptor goes into the back of the stereo and the other end goes into the back of the usb output.

But I'm struggling one how to get access to the back of the usb output. Please a quick tutorial on how to get to the back of the usb output is all im asking for.
