For installation, refer to the Alternate Trash Installation document inside the Alternate Trash Cans folder. Follow the INSTALLATION WITHOUT AARON if you do not have Aaron and the INSTALLATION WITH AARON if you do have Aaron. Just edit other resources, not the ones mentioned. These edit the Trash. By looking at the icons you should be able to tell where to put each one.
A GOOD ICON TRICK:
To trick someone with a Mac, install icons where they shouldn't go, like an Extensions icon on the Control Panels Folder and vice versa! A good April Fool's Joke.
