Are you asking if you need a wiring harness? If so, then you don't NEED one but it's highly recommended to avoid hacking the factory wiring and to make things easier. And yes, you do need an antenna adapter to use the FM radio on an aftermarket deck.
Edit: I looked up Eonon decks and the harness they use is interesting indeed. It looks like you should be able to cut that plug off and splice into a wiring harness that plugs into the factory harness. I am not 100% sure on that though.
