- the two wire harnesses are classified into a base circuit shared by all car types and an add-on circuit different depending on the car type.
- the base circuit portion and the add-on circuit portion are assembled on another assembly work table, and then the base circuit portion and the add-on circuit portion are overlapped and bound at a required position to complete the optical harness.
- the base circuit portion can be shared by all vehicle types, and large-lot production can be performed at low cost.
- design and manufacturing cost since it is sufficient to prepare only the add-on circuit portion for each vehicle type, design and manufacturing cost As a result, it is possible to reduce the variety of divided circuit parts before bundling in a wire harness and to reduce the burden of part number control.
- the base circuit part should be shared as it is, and only the add-on circuit part needs to be designed and manufactured.
- the period can also be shortened.
- the assembly workbench for the base circuit has a length greater than that of the second assembly workbench for the add-on circuit, and the base circuit is assembled when assembling the add-on circuit portion on the second assembly workbench having a short length.

- Each front harness WZH3 and WZH4 includes a base circuit sub harness 10 which is a common base circuit portion and a first add-on circuit sub harness 11 or a second add-on circuit sub harness 12 which is an add-on circuit portion different for each vehicle type. It is united and formed. That is, the first add-on circuit sub-harness 11 and the second add-on circuit sub-harness 12 have different wire lengths due to different mounting positions of the electrical devices (such as lamps) to be connected, and wire portions having different branch positions. This includes the parts where the number of electric wires connected with the connector C connected to the terminal is different.
- the base circuit sub-harness 10 is continuous to the rear cross section 1 Ob along the dash panel P of the engine room X and to both ends of the rear cross section 1 Ob.

- the first add-on circuit sub-harness 11 is a second assembly work table for an add-on circuit whose width W2 is smaller than the width W1 of the assembly work table 13 for the base circuit.
- the electric wire that constitutes the part not connected to the base circuit portion 10 in the later process is wired through the electric wire receiving jig (not shown) erected from the second assembly work table 14 while the base circuit sub A portion A connected to the harness 10 is assembled and tied in a state of being dropped between wire support jigs (not shown).
- the first add-on circuit sub-harness 11 assembled in advance as described above is combined with the base circuit sub-harness 10 on the assembly work table 13 for the base circuit. Align and lay it up repeatedly and tie the required position to form the front harness W / H3 of the first car type. At this time, the parts not connected to the base circuit sub-harness 10 on both ends of the first add-on circuit sub-harness 11 have already been completed, so final assembly work is possible in a state where the assembly work table 13 for base circuit protrudes. Therefore, the width W 1 of the assembly work table 13 is also short and space saving can be achieved. In addition, since the assembly workbench 13 for the base circuit is used as an assembly workbench to perform the final binding work, there is also a merit that it is not necessary to prepare a workbench for the final assembly work separately.
- the second add-on circuit sub-harness 12 And the left and right sides 12a and 12c which longitudinally cross the left and right sides of the engine nose X continuously to the both ends of the rear cross section 12b and the front ends of the left and right sides 12a and 12c.
- the rear end portion 1 ⁇ 4 of the left side portion 12a is connected to the junction box J in the room Y and the connector C through the dash panel P so as to penetrate the rear end portion 1 ⁇ 4 of the left side portion 12a.

- the design and manufacturing costs are reduced, and the more models there are, the more the models are divided into the front harnesses W / H3 and W / H4.
- 1st ⁇ 2nd add-on circuit sub-harnesses 11 and 12 can be greatly reduced, and the burden on part number control can be reduced.
- Sub harness 10 Since it is only necessary to design and manufacture only the add-on circuit sub-harnesses 11 and 12 as they are, they can be flexibly handled and the production preparation period can be shortened.
- the electric wire at the portion to be connected to the base circuit sub-harness 10 is a wire Since the assembly is made to hang between the receiving jigs, the width W2 of the second assembly work benches 14 and 15 can be reduced by the length of hanging the electric wire, and the work space can be made more efficient. Further, even if the lengths of the add-on circuit sub-harnesses 11 and 12 differ among the vehicle types, it is possible to share the same second assembly work benches 14 and 15 simply by changing the hanging length of the electric wire.
- an assembly work table for binding is used as an assembly work table for finally bonding the base circuit sub harness 10 and the first and second add-on circuit sub harnesses 11 and 12 to form the front harness WZH3 and WZH4. It may be provided separately. Then, the size of the separately provided assembly work table for binding may be provided in a range that covers at least a portion where the binding operation of the base circuit sub harness 10 and the add-on circuit sub harnesses 11 and 12 is performed. The installation space of the assembly work table for binding can be reduced.
