Normal Operation
The central junction box (CJB) provides voltage to the headlamp switch through circuit 29-LE29 (OG/BK). When the headlamp switch is placed in the PARKING LAMPS ON position, voltage is routed to the front parking and side marker lamps through circuits 29S-LF3 (OG/YE), 29S-LF7 (OG/BU), 29S-LF8 (OG), 29S-LF16 (OG/GN) and 29S-LF17 (OG/WH). Voltage is also routed to the rear parking and license plate lamps through circuits 29S-LF11 (OG/WH), 29S-LF20 (OG), 29S-LF21 (OG/WH) and 29S-LF22 (OG/BK). Ground for the front side markers is provided by utilizing the turn lamp circuitry and filaments. Ground is provided through circuits 31-LG11 (BK) and 31-LG18 (BK) to the LH and RH front parking lamps, respectively. Ground is provided through circuits 31-LF23 (BK) and 31-LF24 (BK) to the LH and RH rear parking lamps, respectively. Ground is provided through circuits 31-LF21 (BK) and 31-LF22 (BK) to the LH and RH license plate lamps, respectively.
