To provide a connection method and an electrical unit for cost reduction.SOLUTION: A wire harness W1 is used to connect a plurality of switches 2 and a control circuit 4 that determines each of the states of the plurality of switches. Multiple types of wire harness W1 having a terminal 111 connected to each of the plurality of switches 2 and having a connector C21 having a built-in input circuit 11 that converts on/off signals of the plurality of switches 2 into serial signals and outputs them, having different numbers of terminals 111 are prepared. The wire harness W1 in which the input circuit 11 having the number of terminals 111 corresponding to the number of the plurality of switches 2 is built in the connector C21 is selected to connect the plurality of switches 2 and the control circuit 4.SELECTED DRAWING: Figure 1

    【課題】コストダウンを図った接続方法及び電装ユニットを提供することができる。【解決手段】複数のスイッチ2と、複数のスイッチの状態を各々判別する制御回路4と、の間を、ワイヤハーネスW1により接続する。複数のスイッチ2に各々接続される端子111を有し、複数のスイッチ2のオンオフ信号をシリアル信号に変換して出力する入力回路11が内蔵されているコネクタC21が取り付けられているワイヤハーネスW1を、端子111の数が異なる複数種類用意する。複数のスイッチ2の数に応じた端子111の数の入力回路11がコネクタC21に内蔵されているワイヤハーネスW1を選んで、複数のスイッチ2-制御回路4間を接続する。【選択図】図1
