Verify that the plug is completely plugged into the controller, and that both clips at either side are completely engaged. These can be rather snug, and can require some extra pressure to properly plug in. Also, verify that none of the pins are backing out of the original plug. You would want to take a pair of pliers, and push in all of the wires at the controller plug to make sure that they are not backing out.
