Access to rear vent above window

[forwheeler]

I want to install a 3rd brake light (LED strip) above the rear window trim outside where the cabin vent is. I want to be able to fish a wire to inside the car from outside. I unzipped the sunroof access and I can't see how to access the area. I would like not to remove the headliner to so this.

Is there a way to do this?

Do not know about the air vent.
I did mine while I had the rear window out during a repaint.
Did run the wire along inside the rear window seal.

So you ran the wire from outside the car to inside when you had the window out then?

Where did you get that valence above the window with the light in it?

I've never seen that rear window valence before, but I like it

Also noted the RarelyL8 exhaust...looks great as well.
