Abstract: A guide jig having a novel structure capable of being fixated quickly and easily on a wiring diagram without damaging the wiring diagram and also capable of achieving a powerful fixative force when fixated on the wiring diagram. The guide jig includes a magnet body magnetically held to a diagram board main body, a wiring diagram being provided to the diagram board main body, and a support placed on the wiring diagram. A guide on which a wire harness runs is provided between the magnet body and the support. The support includes a friction member preventing the support from slipping with respect to the wiring diagram.

Abstract: A waterproof structure and a waterproof method for a wire connecting part, wherein the insulating coatings of a plurality of wires are peeled, and exposed cores are connected to each other by welding, soldering, or through a crimp style terminal. A foam sheet impregnated with a silicone and an adhesive tape are wrapped around the connecting part, and the silicone is filled in clearances between the connected cores.
