If it does where is the location? If not do I need an interface wiring harness for aftermarket stereo system. And need a wiring diagram for factory stereo amp speakers. Thank you!

If you have the premium audio system then you do have an amp and it is located in behind the right quarter trim panels. I attached the process to remove it and the wiring diagrams. The first two are the base radio system (non amp) and the next two are the premium system that does have the amp.

If you have the base system then yes, you will need a wiring harness to route your speakers through the new amp.

Let me know if you need more info and I can send that over. Thanks
