From that angle I can't tell if that's an IDC or not.
Either way, the whole thing needs replacing.
You'll have to snip the wires back ~1/4 inch from the connector (or wherever the insulation looks good closest to it). Bare the ends of the wires, crimp on new pins, and slide them into a new housing.
I don't have parts numbers handy, but I'm sure someone that does will chime in shortly.
