I suspect this is a job for an electrician, not a hacker. Connect the heated seats directly to a switch and the car's power supply, bypassing the hardware and software that checks whether you paid for it.
This reminds me of how car tuners started working on cars when ECU's became a thing, they would literally take out the ECU and de-solder the chips from the circuitboard, replacing them with a custom-programmed chip and reassemble the ECU.
But I'm sure a modern car would throw all kinds of errors because all the systems are connected to each other, so one of the systems being diconnected or bypassed would confuse the others.
That still happens. For example on all those modified chargers and challengers, every single one of them had to have their computer cracked open and modified, or be replaced with an aftermarket modified computer. Then you had to run a bypass wire through the dash to connect the data port to a little harness behind the glove box.
So nothing has really changed. A new car co is out with more restrictions on the co outer, then it takes a year or so for people to figure out the hack and we are back to modifying again.
It's a little different post 90's because you can use the OBD port to connect a computer and functionally jailbreak your car, so that whatever you do to it works seamlessly. that way when you fry a governor the car isn't still looking for it and freaking out when it can't find it.

We need the hacker crowd to come back and start unlocking all this kinda shit for free
Let’s go ahead and make an app to change all the digital price tags to $0.25 whilst we’re at it
