Just a heads up, those diagrams are also insufficient on their own. They don’t indicate which line goes to the wide blade and which goes to the narrow blade on the plug. Getting that backwards on some devices can cause switching and fusing to be on the wrong line and defeat certain circuit and safety protections.
Much as I encourage people to fix their own things, wiring AC mains connections is one of those “if you have to ask, you probably shouldn’t” kind of things.
