This circuit originates in the Power Distribution Center (PDC) and is protected by a 40 Amp fuse located in cavity 14. The headlamp switch has a LOW beam and HIGH beam select position.

Power for the parking lamp portion of the headlamp switch is provided on circuit F33. Circuit A13 in the Power Distribution Center (PDC) powers a 20 Amp fuse located in cavity 7 of the junction block. The A13 circuit is protected by a 40 Amp fuse located in cavity 14 of the PDC. Circuit F33, which connects to the other side of the fuse in the junction block, connects to the headlamp switch and is spliced to provide power for the instrument cluster.
