The easiest way to remove the machine from the cabinet is to undo the screws in the bottom of the controller. There will be two screws on the attaching the cord. Remove them, and slide the cord out from the hole in the mechanism.
I just rewired a 15-91 a couple of weeks ago. You can purchase replacement cords from sew-classic.
