Aux Audio Input

[F-100 Hun]

2008 F250 XL. I upgraded from AM/FM to the same with CD, both Ford. I would like to have aux input. Lower right center dash panel, mine came with the blank (and black) panel with the wire attached to the back, just no aux input plug. Do you have to buy the panel with the input plug, just the plug and open a hole in the panel, or what? The parts guy was no help whatsoever. Any advice or better yet a part # would be great.

Does the blank one have this frame around the plug? or is it flush?

Negative, it is flush. I think what you have is what I am looking for.
