hi
if the little metal connector is still on the end of the wire then it should just push back into place. I can not see it in your pic very clear as i am viewing on a mobile.

If the wire has snapped away from the metal tang then you will have to solder the the wire direct to the chip board or get a new connector.

These plugs are called from memory jst , i started a thread some time ago and a member did find a supplier for them.

hi
nice one Mars.

there should not be any need to solder anything on these connectors as the name mentioned above (JST) stands for from memory Japan solderless technologies.
