Abstract: With the increase of automobile functions, the electrical architecture becomes more complex, and the complexity of the vehicle harness system also increases. The increase of vehicle harness circuits leads to the increase of vehicle harness volume, the thickening of trunk and the hardening of harness. In order to perfectly embed the harness into the vehicle body in a limited space, avoid the harness being squeezed, pulled, and rubbed, and ensure the normal function of the vehicle electrical appliances, the layout of the vehicle harness needs to be designed and studied. By introducing the failure mode of wiring harness layout and combining with the practical wiring harness development experience, a reasonable wiring harness layout development scheme is provided to improve the reliability of wiring harness from the perspective of layout, which can effectively avoid the risk of fire caused by functional failure or short circuit and provide a reference for the layout development of new vehicle wiring harness.

Key words: Vehicle harness; Harness short-circuit; Harness reliability; Harness layout
