Abstract

Embodiments are directed to a cable harness. The cable harness may include a female connector, a male connector, main wires, and branch wires. The female connector and the male connector may each comply with a Society of Automotive Engineers (SAE) J1962 standard and may each have a plurality of pins. Each of the main wires may electrically couple a respective one of the pins of the male connector to a corresponding respective one of the pins of the female connector. Each of the branch wires may electrically couple to a respective one of the main wires via a respective T-splice. A first pair of the branch wires may provide a branch connection to a first Controller Area Network (CAN) bus wire combination. A second pair of the branch wires may provide a branch connection to a second CAN bus wire combination.
