The Harness Box is the connection between your car and your A1/C3X/C3 or between Black Panda and your car.
It enables a non-invasive connection and should be connected to your vehicle using a harness cable.
To complete the setup, ensure the Harness Box is also connected to the OBD Power using an RJ45 cable.
Lastly, use the USB-C port on the Harness Box to connect it to your A1/C3X or Black Panda.
It fits all the connectors as previous relay box. Its easier to fit into your car since all of the cables are aimed same direction.
This harness box is a new version designed and made by Springer Electronics.
Note:
This harness box fits all harness cables that were sold prior to October 2024 by Comma. (Comma changed standard to a smaller harness cable connector in October 2024)
