Have to tell on myself. Cannot buy my Prius just yet. Probably weeks away. Couldn't help myself. Went to Radio Shack and bought my EV Button ($2.69) and a package of tap splices ($1.99). I have the wire already. So, I have my EV button before getting the car. Don't worry, I won't install it right away or overuse it. I am convinced it will help in some specific frequent situations in my driving. Once I get past initial warranty issues, establish some baselines, and confirm what I've read in my own usage, I'll install it following efusco's paper at calcars: http://www.calcars.org/prius-evbutton-install.pdf Modifications: EV Button Car ownership: No
