If you need assistance in figuring out what each of the connectors do on the back of the radio, please reference this image. The fakras have different colors and are used for different purposes. Not all will be using when upgrading because the factory system may not have some of the newer features that come with this radio from factory, as well as the color change in generation from Curry to Blue for GPS/XM.
