What I mean is this: the ends of those wires (the ends that are connected into the connectors) look brittle and unflexible. Pull each wire out of it's slot, cut it off (cut off the brittle ends, like an 1/8 of an inch), and restuff them into their slots using the punch tool.
Be careful using that tool. I'm anticipating you having trouble punching the wiring back tight as you won't have a good hard surface to use. You'll have to use the palm of your hand to hold the connector. WHen done correctly, the wire will sorta pop down into place. Problem is is that those connectors are sometimes brittle. Try to be careful.
