I have seen threads in various places that show how to make an EV button for the Prius II. I find it interesting, but I don't know that it would be useful in my day to day driving. I recently got a chance to drive a 2010 Prius (compliments of Bob Wilson), and got to try out the EcoMode. This got me wondering if there is a simple EV button style modification I could make to activate EcoMode. I also tried out the PowerMode, but really don't think I would use that in my day to day driving! Any help would be more than appreciated. Thanks.
