A hinge pin includes a pin body, a first electrical connector located at a first end of the pin body, a second electrical connector located at a second end of the pin body, and electrical conductors that electrically connect the first electrical connector and the second electrical connector. The hinge pin may be incorporated in a hinge to connect a first hinge part and a second hinge part for rotation. The hinge may be incorporated in an apparatus in which first and second wire harnesses are connected to the first and second electrical connectors of the hinge pin by third and fourth electrical connectors.
