Hello!
I just hit the junkyard lottery and found mint condition 2012 KK arctic edition heated power seats, and I’ve started to look at how to install them. The biggest problems I’ve ran into are the back sear not fitting at ALL, and the heated sear conrols being mounted on the dash under the heat and ac controls in the kk but in the kj they are on the seats themselves. Would I be able to transfer the old controllers and the old plugs to my new seats? TIA

They are but a little bit of plastic needs cut from the center console.

For the heated seats... sure with a good wiring diagram and some electrical surgery, it'll probably work (assuming no voltage difference between seat controls, etc.). For the rear seat frame not fitting, that's a no in my book.

I’ve figured out my backseat issues. I have wiring harness and controls for the original seats that came out, I jest need to switch plugs and figure out what goes where. Thank you!
