Interfaces and components

To make it easier to tell them apart, the system connector is white for the vehicle electrical system BN2020 and black for the vehicle electrical system BN2000. The Combox is connected in the L2 and L4 to the K-CAN and in the L6 to the K-CAN2. Because the K-CAN and K-CAN2 have different speeds, the color-coding was implemented to prevent them from being mixed up.
