Hi, I am having to replace the windshield on 2019 RAV4 Hybrid Ltd. thanks to a dump truck rock attack. I am looking to see if I can take this opportunity to install the heated windshield. I have purchased the interior switch (part 84794-0R030; SWITCH, WINDSHIELD H) and I am trying to find how to install the switch and related necessary fuses, then I will ask safelight to install the heated windshield instead of the regular one, I assume the 'plug' for the windshield is already in place.... Is this doable? Any guidance, pictures would be most appreciated...
