Exterior Lamps

PARK, MARKER, TAIL AND LICENSE LAMPS
Voltage is applied at all times from the PK LPS Fuse to the Headlamp Switch from ORN (240) wire. With the Headlamp Switch in PARK or HEAD, voltage is applied to BRN (9) wire. Current flows through BRN (9) wire to all Park, Side Marker, Tail and License Lamps turning them ON. The only lamps that receive current from BRN (9) wire and do not turn ON are the turn filaments in the Park/turn Lamps. They do not turn ON because the voltage drop across the Front Side Marker Lamps is much greater than that across the Turn Lamp Filaments.

TURN LAMPS
With the Ignition Switch in the RUN or START position, voltage is applied from the Turn-B/U Fuse to the normally closed pole of the Hazard Switch in the Turn/Hazard Switch. With the Turn/Hazard Switch in the LEFT TURN position, voltage is applied from the Switch to the LT BLU (14) wire and to the YEL (18) wire LH Front Turn, Rear Turn and Indicator Lamps flash ON and OFF as current flow is controlled by the Turn/Hazard Flasher Module, and it continuously opens and closes the circuit (for RH Turn Lamps DK BLU (15) wire and DK GRN (19) wire). With Park Lamps ON and Turn Lamps ON, voltage is applied to both Terminals of the Front Side Marker Lamp causing is to be OFF. When the Front Turn Lamp is OFF, voltage is applied to only one Terminals of the Marker Lamp, causing it to flash ON. The Turn Lamp and Marker Lamp continue to flash ON and OFF in sequence until the Turn Switch is turned OFF.

HAZARD LAMPS
Voltage is applied at all times from the STOP/HAZ Fuse to the normally open poles of the Hazard Switch in the Turn/Hazard Switch. With the Hazard Switch in HAZARD, voltage is applied to the Turn Lamps. All of the Turn Lamps and both Turn Indicators flash ON and OFF.

STOPLAMPS
Voltage is applied at all times from STOP/HAZ Fuse to the TCC/Stoplamp Switch. When the Brake Pedal is depressed, voltage is applied from the TCC/Stoplamp Switch through the Turn Signal Switch to WHT (17) wire turning ON the LH and RH Stoplamps. When the Brake Pedal is depressed, voltage is also applied from the TCC/Stoplamp Switch to the Center High Mounted Stoplamp (CHMSL) through the WHT (17) wire turning ON the CHMSL. The Center High Mounted Stoplamp is not affected by the Turn Signal Switch operation.
