Headlamps
The headlamp switch has three positions: ON, PARK (parking lamps) and OFF. Circuit A3 from fuse 5 in the PDC connects to the headlamp switch and feeds the circuit L7 through fuse 15 in the fuse block. Circuit L7 connects to the headlamp switch.Circuit A3 also splices to feed circuit L11 through fuse 4 in the fuse block. Circuit L11 connects to the dimmer switch circuitry in the multi-function switch.
Circuit A3 from fuse 5 in the PDC supplies battery voltage to the headlamp switch. The headlamp switch has an internal circuit breaker that connects circuit A3 to circuit F34. Circuit F34 connects to the dimmer switch circuitry in the multi-function switch.
