    Hi folks,

    Does anyone know if the base car (Prius Two) comes prewired/with a harness to install a Homelink mirror from another Gen3 Prius? Or has anyone tackled this project successfully?

    Thanks!

    I’ve installed one in mine.

    It’s rather easy actually. There’s a connector in the driver’s kick panel with both an ignition hot and battery constant wire which I piggybacked off of. Given the low current draw of the device, I wasn’t worried about overloading an existing circuit.

    On a 2011 prius, this black connector in the kickpanel had constant hot (red) and ignition hot (blue)

    Cool, thanks! Question, would it not be easier/possible to draw power from the dome lights, which are closer to the mirror? How’d you go about routing the wires from the kick panel?

    I forget which ones is lacking in the dome assembly, but you need both ignition hot and a wire that’s 12+ at all times.

    Pull the door weatherstripping next to the dash, and pop the A-pillar trim loose. Tuck your wire up over the edge of the headliner across the top of the windshield. Then route it behind the airbag in the A-pillar down into the kick panel.

    Not sure what’s funny - many cars come prewired since a Homelink/autodim mirror is often optional, and this is where the prewired harness would be found.

    Sure! This is literally a 15 minute install. Half an hour if you take your time.

    Those of you who have done this successfully, could you point me to the mirror you used please?

    Any mirror will work. There are only two wires to be connected for the base mirror with homelink but more if you purchase a mirror with a small LCD screen for backup cam image.

    The color on this one (compass comes in different colors) matches a prius’s blue-green interior. Looks 100% factory, and opens your garage. And the auto-dimming works flawlessly. Which you’d expect: these are a factory offering in Tacomas, Avalons, Lexus’s, etc.

    I like one subtle security feature: your ignition has to be on in order to power up the mirror. So no one can break into your car and use the garage door opener to gain access to your home.

    Once you install it, look up “homelink mirror reset” on Youtube and then “homelink mirror compass calibration” and “homelink mirror programming.”
