Normal Operation

When the headlamp switch is turned to the ON position, the smart junction box (SJB) monitors input from the instrument panel dimmer switch. The SJB then sends the instrument cluster a variable voltage on circuit 1418 (LB/WH). The instrument cluster is grounded on circuit 1205 (BK).
