Do you have a recipe for Jello Light and Fluffy Pie?

Many years ago I used to make something called “Light and fruity” pie. The recipe was on every box of Jello.  The simple recipe consisted of a graham cracker pie crust, Jello, and Cool Whip, and lots of ice cubes. Do you remember this delightful desert?  Do you happen to have/remember the instructions for making the Jello/Cool Whip filling?  Also, I wonder if the same could be done with pudding. I shouldn’t have sugar, and was going to try sugar-free Jello for this. Any help is greatly appreciated!
