Hello, my truck has been making the " parking brake on" buzzer noise even when the air is filled up and the parking brake is popped up. I replaced one switch there that was right under the cup holder hoping that would be it but it keeps buzzing even when its filled with air.. but there are about 5 more there. Can someone help me identify it? I attached pictures of the manifold to see. What would be connected to it? would it be a green or yellow hose or a cable or what. The truck is a 2001 freightliner century. thanks
Which switch is the parking brake switch
