The car harness is our universal interface to your car. Use the car harness to connect the comma two to your vehicle. We designed it to be almost invisible in your car while being easy to install and use. Car harness includes comma power with VIN fingerprinting capabilities, a harness adapter with automatic switching to stock, 1 RJ45 cable (7 feet), and 1 USB-C to USB-C cable (1.5 feet). For all other devices, except the comma two, you may want to purchase the black panda with high precision GPS and OBD-C (the new standard port for comma hardware).
