Can I install heated power in 2019 trd

Id like to have heated seats, with lumbar support, power.
So I was wondering if I could install tundra limited seats in my 2019? Would it matter what year the seats are. Im looking for used seats! How hard would it be? Where is a good place to start looking for seats?

Yes I'd love a new limited trundra but the prices are higher than new to me seats.
Thanks for your help.

 

Probably won't help much, but the original buyer of my 2019 must have had them put in my truck by factory or dealer.
Mine is a crewmax SR5 TRD offroad that shouldn't have heated seats. The drivers seat is also full electronic.
The heat switch for the seat is a simple on/off for each seat. It is located at the bottom of the dash just forward of the shift lever next to the usb port where the manual only shows a blank spot for all models. Looks like a factory switch though.

I would have to imagine that it would be possible to change out the seats provided the wiring harnesses are in place.
Try the search feature, maybe there is a thread buried somewhere.
Edit...
Maybe this will help

It appears there are also kits available to convert existing seats, but definite warnings and precise directions regarding airbags. Makes me think original buyer had mine done by dealer. One of the links shows a slightly different switch in the same location as mine.

 

Thank you, same truck that I have.
