The car harness is our universal interface to your car. Use the car harness to connect your comma device 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 v2 with ECU 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).
If you are using the car harness with an EON, you must also purchase the black panda with high precision GPS and OBD-C (the new standard port for comma hardware).
