Any of them you will have to put a plugin on the end of the wires. And I don't remember whether the black and white are the power and the green is ground. Just look at the fixture and see what wire is screwed to the framework,that will be the ground. Which Im thunking is the green. And then the other 2 you can hookup to either power side of the plugin. You might check at the local salvation army of a used builders supply store to get them cheap.
