    Hi, I have a 2018 SR5 and a 2016 Limited tundra.
    I would like to take the interior seats and climate control board out of the 2016 and install it in my 2018. Does anybody know if the wiring for the heated seats is already there in the 2018 SR5? And would I be able to plug in the HVAC control panel from the limited into the 2018 SR5? Is the wiring already there or what trouble would I run into? Thank you for the help

    Seats may possibly swap. Though Toyota completely changed the ECU and wiring for 2018 models. if you don’t have power seats now, then there’s a high chance they won’t work. That is assuming that the plugs and wiring is all the same. As far as the climate control goes, it 100% won’t swap over.

    Seat wiring is there, you just have to add a fuse under the hood and switches inside the cabin.
