You will need to buy the dc jack that has the the wire harness on it, the wires in the computer are soldered to the jack so if you try to use them will result in a smaller wire to work with and you will not beable to connect the ribbon from the monitor to the MB

It is absolutely unnecessary to remove all of the screws as shown in the first image, in fact it would be counter productive to do so. One need only remove the screws that have a symbol of either the keyboard, the palm rest or both. The screw locations also have numeral indicators adjacent to them showing the specific size screw for that location.
