Normal Operation - Explorer, Mountaineer
When the headlamp switch is switched to the PARKING LAMPS ON position, the smart junction box (SJB) provides a ground for the parking lamp relay coil.

The parking lamp relay is supplied voltage from the battery junction box (BJB) fuse 2 (50A) through circuit SBB02 (YE/RD). When the parking lamp relay is energized, voltage is sent through circuit CBP26 (BU/WH or WH/BU) to the rear and front parking lamps. Ground is provided to the LH rear parking and license plate lamps through circuit GD149 (BK/GY). Ground for the RH rear parking lamp is provided through circuit GD151 (BK/GN). Ground is provided to the LH front parking lamps through circuit GD120 (BK/GN or BK). Ground is provided to the RH front parking lamps through circuit GD123 (BK/GY or BK).
