I know that the fuse for it is wired in on all models. You would have to find a junked sonic with a heated seat and trace the wiring. Shouldn't be too bad. AC control is acts as the voltage regulator than it might need some wiring and two new seats and done.

Any news since getting the set?

You'll have to run wires to the seats. If you look at the main connector on the bottom of the seat, you'll notice the LTZ has more "pins" populated than the LS.

Good luck.

If you are wanting it to work like factory with the buttons on the HVAC controls then you'll probably need to have whatever BCM that runs those controls flashed also. Like when you add foglights, it doesn't just work automatically.

Well the fuses for it are in every model. If its just a simple switch control then it shouldn't be too bad

OK installed seats plug and play easy, But here comes the but. I put everything together then tried it work perfectly fine now AC doesn't work So I disassembled it to put old unit in the AC works again So I disassembled the complete control model for AC And this is what I found out the both the exact same unit internally Only difference is missing an LED bulb and the switch the goes on the board Look at the picture I posted Now I'm thinking of soldering on the switch and the LED on my original unit hope that works Will keep you posted when I do that.

That's great news! Good work figuring this out, this is the perfect time of year for heated seats

Did you compare plugs on the seat connectors before installing them? The RS seats I installed in my LT had more pins populated so I assumed the extras were for heated seats and that I'd have to run wires with the harness for my car.

Yes I Did compare them they had about 5 more pins than mine but if u look at the plug connector on the car, that one has all wires up to there. So the only thing that changes is the seats and AC control unit so It can work 100% Now make sure when you replace the AC control unit you do your research and it matches the year of the car Because the 1st AC unit control I purchased was a 2014 But for some reason Everything worked except for the AC it would not turn on so I bought a second one that part # said was for 2015/2016 then everything works 100%
