Day two, mod #2.
I took the Prius to the EV build day in Milwaukee. The guys had a lot of questions about it. I also wanted to install and EV mode switch since its a zero cost mod and will come in handy from time to time. Anyway, it was a quick an easy install. All you need to do is put a momentary switch inline with a pin on the EV ECU and ground the other end. It took all of ~30 minutes to do. I have pics on Ben's camera, so when I get them, they'll be posted.
