Definitions

  • the application relates to a harness for engine compartment wiring of a motor vehicle.
  • Combustion engines are regularly fully wired before installation in a body. Wiring connects the generator, starter, spark plugs and other electrical loads in the engine. Furthermore, connection points are prepared for cabling with a battery as well as for cabling with other electrical components. To do this, the vehicle fitters have to lay harnesses around the engine block in complex and time-consuming procedures in order to ensure the necessary wiring of the electrical components. The cabling of the electrical components of the motor or the engine block takes place with the aid of prefabricated cable harnesses. In these harnesses, the necessary cables are already provided cut to length, so that only the terminal ends of the cable must be contacted. This is done regularly by screwing or soldering the terminal ends of the cable to the corresponding contacts of the electrical components in the engine block.
