電装システムの主要部の電気回路の構成例を図1に示す。図1の電装システムにおいては、図2の例と同様に、ワイヤハーネス本体10の一端が電源制御ボックス21と接続され、ワイヤハーネス本体10の他端が電源制御ボックス22と接続されている。すなわち、ワイヤハーネス本体10の4本の電線11a、11b、11c、および11dのそれぞれが、電源制御ボックス21および22と接続されている。
電源制御ボックスの外観の具体例を図5に示す。図5に示した電源制御ボックス90は、ボディ系のモジュールを制御する機能を有する電子制御部91、および車両の走行系およびオーディオ系のモジュールを制御する電子制御部92を内蔵している。また、この電源制御ボックス90は、ワイヤハーネス本体10の一端と接続する可能な出力側接続部93を有し、更に主電源30および上位ECU40と接続することが可能な入力側接続部94を有している。
例えば図3に示した電装システムにおいては、多数のモジュール51~58のそれぞれが、ワイヤハーネス本体10内の1組の電線(11a~11d)を電力供給および通信のために共有することができる。従って、接続するモジュールの数が増えても、ワイヤハーネス本体10を構成する電線(11a~11d)の本数を増やす必要がない。そのため、ワイヤハーネス本体10の外形形状が太くなるのを防止することができ、重量も減らすことができる。
