Wiring harness assembly and method of making same

A method of making a wiring harness assembly, the method comprising:

• preparing a visual representation of a wiring harness diagram comprising:
• providing a main trunk of main trunk wires running along a same pathway and one or more branches or branch wires extending from the main trunk at one or more attachment sections along the main trunk, the main trunk wires and the branch wires being connected at connecting points within one or more attachment sections;
• delimiting one or more intersections along the main trunk, each of the intersections comprising a respective one of the one or more attachment sections and a plurality of proximal portions, at least one of the plurality of proximal portions comprising a portion of the main trunk contiguous with the attachment section, at least another one of the plurality of proximal portions comprising a portion of the branch contiguous with the attachment section;
• grouping the main trunk wires to define a main trunk cable defining a terminal end thereof at one of the proximal portions;
• grouping the branch wires of each branch to define a respective branch cable, each respective branch cable defining a respective terminal end thereof at a respective one of the proximal portions;
• providing a connector for each of the intersections for housing therein the attachment points and providing terminal ends at the proximal portions for connecting to the terminal ends of the main trunk cable at of the respective branch cables;
• and
• molding connectors, each of the connectors comprising with respective segments of interconnected main trunk wires and branch wires and defining terminal ends for connecting to cables in accordance with the wiring diagram;
• preparing main trunk cables and branch cables in accordance with wiring harness diagram;
• assembling and connecting the connectors, the main trunk cables and the branch cables in accordance with the wiring harness diagram.
