I have a 2012 and got almost everything I needed at of all places "Walmart" they had the Schosche adapter and the wiring harness. If you don't have the correct adapater for your antenna check autozone or another local parts store they usually have a variety of them. On a side note. I do not recommend the Schosche. I had to disconnect my battery and now my Jeep is throwing a "lost communication with radio code". The "fix" involves me opening up the dash to reset the module, no thanks. I don't think the code is hurting anything. I hope this helps.
