I will try and get a picture in a few, but on the bottom side of the frame on the passenger side of my 2000 Trans Am there is a black plastic tube that looks like it has a plastic vacuum line that comes out of it and going into the wiring harness. It is sitting next to the horns. Anyone know what it is and how to disconnect it? I'm trying to move the wiring harness and the piece it to large to move. I tried pulling the tube but I don't want to break it if it is important.
