Going with the xAC by itself, it’ll be best to control one thing only. In this case I’d suggest unlock. You just won’t be able to lock via swipe, but you should be able to do that while getting out of the car.
In a nutshell, hook up the unlock wires to the solenoid on the xACv2. Everytime you swipe it should unlock. You’ll have to mount stuff and extend some wires, but not that complicated.
There’s also this. If you wanna go all in on electrical.
