I have been doing serious work to my cars interior( installing, sound deadener along floor trunk, and doors, re-ran wires from the dash back to get space, and installed a new stereo). My problem is that when I unpluged the wires from the metal box to the left and above the dead pedal, and then plugged them back in later a few major things no work such as windows, interior lights, and my beeping thing that tells me my keys are still in the ignition. I do know a few things for sure and those are i never splice, cut, or modifide any of the wires tht control the things that are not working. It seems that its definetely the box thatthe wires ere unplugged from thatis cause this problem but unfortunatley I have no idea how to fix it. PLEASE help I need windows.
P.S. the horn also has a distingtively high pitch now where as before it too was normal.
