I would like 2 use a plug where the antenna used to be, where can I obtain one

What is your question?

The antenna got stolen so that means there is a hole where it used and that equal's to water in the trunk if I take the special tape off (which looks stupid). Funny enough I shoved the antenna connect parts right up straight into the wheel well and the radio is quite clear. I just need to seal it up with a correct kind of plug, so I can order one. Also where may I obtain it. Thank you

What makes this problem better or worse?
