PURPOSE:To facilitate a wiring operation and maintenance and improve the advantage on waterproofing by connecting an outdoor side harness to an indoor side harness on a nearly horizontal partition wall part between the outside and inside of a room. CONSTITUTION:Since a joint box 4 is installed on a dash board 3 between the inside of a room 1 and an engine room 2, an outdoor side wire harness 7 may be collectively wired to a relay box 10 on the outside of the room, and an indoor side wire harness 12 may be collectively wired to a connector 11 awaiting the harness 12 on the inside of the room. After that, the relay box 10 is joined to the awaiting connector 11 to complete wiring, making an wiring operation extremely easier. Also, in maintenance, the relay box 10 can be easily separated from the awaiting connector 11 and, further, the relay box 10 which is internally provided on the upper part of the joint box 4 facilitates the check of wiring and the replacement of fuses. |
