Abstract: Engine factory test is the key to verify its performance and reliability. Facing a wide variety of connectors and their assembly requirements, the structural design of the test harness directly affects the efficiency and accuracy of the test. Aiming at the problems existing in the process of wiring harness connection testing, this paper adopts a combination wiring harness architecture of "main line + function assisted wiring harness". Through sorting out the function definition of the existing electronic control system pins and integrating links of connectors, the wiring harness connection is standardized and modular design, which reduces the types of parts and realizes the universality and interchangeability. With the help of highly recognizable wire harness coding management, the path of wire harness is clear, the identification process of assembly workers is simplified, and the risk of misoperation is reduced. The test results show that the optimization scheme effectively solves the problem of low efficiency of connector assembly in engine bench test, improves the stability of signal transmission, provides an efficient and reliable solution for the engine test field, and reduces the upgrade and maintenance cost, which has high practical application value and promotion prospect.
