Description

Technical Field

[0001] The present application relates to the technical field of diesel engines, and in particular to an integrated wiring harness for a diesel engine and a diesel engine thereof. Background Art

[0002] When existing diesel engines are used on vehicles, they need to be equipped with a variety of electrical parts. The engine is the main power source for various electrical devices, and each electrical part must be connected to the vehicle control end wiring harness. When each electrical component is electrically connected to the engine through the wiring harness, the wiring harness branches in the chassis area are complicated and prone to assembly errors.
