W126 What the heck is this?

I was working on my radio and took off the inner driver kick panel for easier access and visibly of wire interference with the ash tray. I then noticed that near the floor at the trans body housing there was what I can only describe as a miniature insulated duct tube. But one side of it was completely worn open. Inside its yellow with a white spiral metal frame. Outside it was a black thin plastic cover. It went up towards the dash.

I have a pic, but before I go through the pain of uploading I thought I would ask.
