Before attempting to remove the connector, use 5 minute epoxy to glue the wires together. Do this in several small batches and apply with a toothpick, right up to the plastic connector, but not glued to the connector (to risky and not necessary). Be especially careful not to glue to the motherboard. You basically want all 5 wires glued together as if they were a ribbon cable. After the epoxy is cured, pry up from underneath the wires to remove from the motherboard.
