All wiring harnesses are required to be neatly routed, firmly fixed, free from swaying and hanging, free from interference force, and free from frictional damage. In order to make the wiring harness layout reasonable and beautiful, various types and sizes of fixed brackets can be used when wiring. When laying the wiring harness, the specific installation positions of various electrical components and plug connectors should be fully considered. Leave the length of the harness.
The wire harness that grows out of the body and is not in use should be folded and reeled, and the plug joints should be sealed and protected, and there must be no hanging, shaking, or load bearing force on the body. The outer sheath of the wiring harness must not break the bellows, otherwise it must be wrapped, and the bellows should be wrapped tightly with tape or cable ties.
The connection between the main wire harness and the chassis wire harness, the connection between the overhead wire harness and the main wire harness, the connection between the chassis wire harness and the engine wire harness, the connection between the top frame wire harness and the rear tail wire harness, and the diagnostic socket of the electric control wire harness must be placed in places that are easy to repair . At the same time, when the plug connectors of various wiring harnesses are bound and fixed, they should be placed near the inspection port that is convenient for maintenance personnel to operate.
