Normal Operation
When the headlamp switch is placed in the parking lamps ON position, voltage is routed to the rear parking lamps, rear side lamps (dual rear wheels),
the license plate lamp and the central junction box (CJB) through circuit 14 (BN). The CJB then routes the voltage through 2 individual circuits. One
is routed through circuit 14 (BN) to the front parking lamps and the other is routed through circuit 14 (BN) to the signal mirrors (if equipped). The
lamps and signal mirrors receive ground through circuit 57 (BK).
