I bought and had this on my 2015 for the six months I owned it (traded on an ELR) and removed it. I'll post a few photos tomorrow, but this is ready to install and you can easily download the PDF to do so yourself. New these are over $300. PM me if interested.
OK, here are photos of the system, ready to be packed back up and shipped out. Harness, hood switch, and ECU. I need to amend an issue unique only to Persona series (or any Prius with side mirror turn signals), that with this installed, the drivers side mirror signal does not activate. I inquired with Toyota and they said that the RES does not yet have a wire in the harness to send power/signal to that mirror. The right side does work. I just accepted it when it was installed. More important to me to have a warm car than a signal repeater. If you don't have these, then it's not an issue for you. Also, this is a link to the installation manual: http://www.toyotapart.com/PT398-47091.pdf
