If the antenna units 13a to 13e are connected, signals can be transmitted and received between the in-vehicle devices, and the pairing operation on the in-vehicle device side becomes unnecessary. Further, in the wire harness 1 of the present embodiment, the first to third antenna units 13a to 13c are incorporated and integrated in the connectors 12a to 12c provided at the ends of the power supply lines 11a to 11c.

(Step S8) The operator pulls out the antenna units 13a to 13e from the insertion portions 40a to 40e of the pairing jig 4, and ends the pairing process.

The method for manufacturing the wire harness 1 of the present embodiment includes not only the step of assembling the harness main body 10 but also the step of pairing the antenna units 13a to 13e. That is, in the wire harness 1 manufactured by the manufacturing method, since the antenna units 13a to 13e are paired, the signal terminals of the antenna units 13a to 13e are connected to the signal input / output units 22 of the in-vehicle devices 2a to 2c. If the 131 is connected, communication between in-vehicle devices is possible via the antenna 132 of each of the antenna units 13a to 13e. Therefore, the pairing operation on the in-vehicle device side becomes unnecessary. In the pairing of the antenna units 13a to 13e using the pairing jig 4, information is exchanged via the signal terminal 131 connected to the second connection portion 42 of the pairing jig 4, so that the antenna or the like is used. Compared with the pairing process by wireless communication via wireless communication, there is no communication failure and the pairing work can be performed smoothly. Further, in the pairing of the antenna units 13a to 13e using the pairing jig 4, a plurality of antenna units connected to the pairing jig 4 can be paired at once, and the in-vehicle devices are individually paired. The pairing operation can be reduced as compared with.

Although the embodiments for carrying out the present invention have been described above using the embodiments, the present invention is not limited to these embodiments, and various modifications and substitutions are made without departing from the gist of the present invention. Can be added.
