I want to move mine to the glove box, so I can use the old spot as a switch panel. I know I can just extend the wires, but what about the actual hoses? Can I just cut them down, since they come from closer to the glove box anyway? Would that effect anything?

Also, I am going to remove the whole air duct system from my car. When I take it out, should I plug the hole there it connects or what? Also, just by removing the main part that goes to the five vents on the dash, will I still have heat, because I heard the heat comes out the bottom. Thanks
