Steper drive wires and screw

[Spudman]

So I’ve just blown my board after following the video on replacing steper drive so before I do it on my new one. Do I swap all the wires or is it just a couple. And what do I do with the screw on the drive. I’ve watched videos and read up on it all but they all go agains what the other one says total newbie here so pls put it simple.
