Already purchased and installed the switch... only to discover that it wasn't pre-wired. Sucks. So I've been searching and came across this thread: Install Cruise Control into Standard 2010 Prius (Japan-Right Hand Drive) | PriusChat ...which navigated me to Rostra's website to gather my info. That then guided me to this video: [removed since I can't post links yet] and these PDFs: [removed since I can't post links yet] But none of them detail the connector pattern for the Gen III Prius. I'm all prepared to do this wiring, but I'm just wondering if any of you can navigate me to a wiring diagram for the ECM connector on this model of Prius? I lost hope when the light didn't come on, but I'm hopeful yet again, thanks to you guys.
I got my hands on a doc with the wiring diagram, but I haven't tried it myself as yet. Will update when I do.
