This came standard on the mid range and up Chev's/GMC 's starting with with 2014. My nephew has a 2014 Silverado/cloth/no sunroof and his came this way from the factory. Able to use his phone to start/lock ,unlock etc.

 

You don't have any parts to make this work. If you want the ability to remote start from your phone and you have factory remote start you will need the following, and I suggest you deal with Fairway Ford. They make it very easy to get up and running.
