1. Do not pull the wiring harness too tightly during assembly (especially when arranging the wiring harness horizontally), to avoid moving the vehicle in a bumpy state, causing the position of the fixed point of the wiring harness to move, causing the distance between the two fixed points to increase instantaneously, thereby extending the wiring harness Causes the internal contact of the wiring harness to pull off/virtual connection, the wire parameter changes, and even the wire is broken.

2. After the wiring harness is assembled, there must be enough clearance around it to ensure that it will not be pressed by other components, and will not be caught by other components and their fasteners. Avoid grounding faults caused by pinching, abrasion or cracking of the wire harness insulation.

3. Do not arrange connectors with the same model and color. Avoid mistaken insertion during the assembly process and damage to the wiring harness and electrical appliances.

4. The connector is arranged in a position that is easy to find, in a position that is easy to operate by hands and tools. In order to facilitate inspection and maintenance, it is necessary to consider the length of the wires of the electrical device according to the actual assembly situation. If the electrical device is installed in a position that is easy to operate on the surface, you can save the wire and directly connect the connector to the component; if the electrical device is installed in a concealed position and it is difficult to repair and disassemble later, you can connect the wires of the electrical device as needed The length is appropriately increased, so that the arrangement of the plug-in parts is convenient for inspection and maintenance.

In the actual operation process, in addition to carrying out the wiring harness assembly work according to these points, we must continue to find problems and develop more methods to solve the hidden dangers that may occur in the wiring harness assembly.
