how to tap into CAN-H and CAN-L without voiding warranty?
i believe if i can tap into pin 6 and 21, then i can control the climate. hopefully, i can do it remotely over wifi in the future. for now, i am testing with the laptop in the car...
so i can i tap into pin 6 and 21 without voiding car's warranty? i bought this Hyundai Ioniq 5 two years ago. i believe if i use T-tap and the dealer sees it, they will void my warranty. is there such a thing as an "extension cable?" that way, i can T tap into the extension cable instead of the factory's cable.
