  • Corresponding connecting strands of the end of the cable harness are electrically conductively connected to the respective plug contacts of the housing within the contact plug-in unit.
  • Such cable strands are often passed along the commercial vehicle through conduits and connected at one end by means of an electrical connector part with a vehicle electrical functional part such as a vehicle lamp unit, a wheel brake system or the like.
  • the cable harness is preferably by means of a further electrical connector part connected to an electrical control unit.
  • the object of the invention is to provide an electrical connector part of the type mentioned in each case, which enables safe manual assembly and fixation to appropriate parts of the commercial vehicle even in confined spaces.
