You mean like water, no not yet but some silicon caulking should seal any gaps and still flex.
It was a bit of a pain in the
as it always is but what I did is ran the wire up the fender which takes some patients, then I cut a small x in the boot with a very sharp box cutter. Next I took out the kick panel, the plastic piece under the dash, and the glove box so I'd have some leverage to pull the wire. Just be careful of the airbag wire it should be marked with a yellow tag behind the glove box. You don't want that going off in your face
I would want you to get your wings that way.
