Abstract
In the automotive electronics industry, demand for low-cost, high strength-to in-service performance for electronic components continues to drive the development of vehicles’ door Wiring Harness (W/H) system for new applications. The problem of the fatigue strength estimation of materials or components containing natural defects, inclusions or in homogeneities is of great importance from both a scientific and industrial point of view. This article gives some insight into the dimensioning process, with special focusing on fatigue analysis of W/H in a vehicle’s door structures. An en-durance life prediction of door W/H was calculated using finite element analyses. Endurance test data for slim test specimens were compared with the predicted fatigue life for verification. The final life expectancy of the component combines the effects of these microstructural features with the complex stress state arising from the combined service loading and residual stresses.

Summary
An automotive electronic system must be able to anticipate the need for reliable and cost effective connection systems. The main function of the door connection system is to distribute the power supply from one system to another system. In automotive cars, it requires a lot of wiring harness systems to distribute the power from one system to another. In a vehicle’s door Wiring Harness (W/H) system, it is more preferred to arranging a passenger compartment than a hinge and a weatherstrip. An opening/closing member is attached to a vehicle by a hinge enabling easy opening and closing of the different moving member. Such members include doors, such as side-doors and rear doors, and other opening/closing members, such as trunk lids. Automotive Wiring Harness (W/H) system is arranged between a door and a body of the vehicle after being mounted on the guide members, and the opposite ends of the guide members are fixed to both the door and the body, so that the movements of the guide member and the wiring harness can follow the opening and closing
