摘要： A connecting structure of a component in a wire harness includes a relay box connected to a circuit at a power supply side and a circuit at a headlamp side, and a control unit connected to the relay box. A connecting section of the relay box is configured to be selectively connected to either one of a headlamp control device and a relay for turning on and off low beam or high beam. Both of the headlamp control device and the relay have terminals of the same shape.
