【Abstract】With the in-depth application of automotive inteligence and networking technologies，the amount of vehiclecommunication information has increased significantly，and ordinarywires canno longer meettheneedsof highspeed and large-capacitydata transmission. High-speed wiring harnesses are widelyused in core modules such as vehicle intelligentnetworking andassistedautonomousdrivingduetotheiradvantagesofhighdata transmisionrate，strongantiinterferenceability，smallsizeandhighintegration.Sincetheflexibilityofhigh-speedcablesissignificantlylowerthan thatofordinary wires，their layout design must met special technical requirements to avoidearlydesign failure ffecting the normal operation of vehicle functions.This paper discusses the composition and classification of high-speed wiring haresses，the principles of3D layout inthe whole vehicleand key technical requirements，providinga reference for the layout design of high-speed wiring harnesses.

【Key words】automotive high-speed wiring harness；3D layout;high-speed cable;high-speed connector; layout principle
