PURPOSE:To simplify the wiring of automobile component parts, by providing such an arrangement that a switching means for controlling the supply of power to specific electrical components from a high capacity current processing circuit section is energized in accordance with a control signal from a low capacity current processing circuit section. CONSTITUTION:A central box connected with wire harnesses from a plurality of electrical components is composed of a high capacity current processing circuit 40 and a low capacity current processing circuit 70 which are connected together through connectors 78a through 78d. The high capacity current circuit 40 is connected with the electrical components such as, for example, a power window unit 56, a rear defogger 85, etc. Relay switches for controlling the supply of power to these electrical components are energized in accordance with a control signal from a computing and processing section 90 in the low capacity current circuit 40. |
