STOPLAMPS
Voltage is always available to the TCC/stoplamp switch from the STOP fuse through CKT 140 (ORN). When the brake pedal is pressed, the TCC/stoplamp switch contacts close, and voltage becomes available on CKT 17 (WHT) to the stoplamps and also to the turn signal switch. The turn signal switch has provisions for connecting to trailer stoplamps through CKT 19 (DK GRN) and CKT 18 (YEL). The center high-mounted stoplamp consists of two bulbs in a parallel circuit. The BLK wires are ground wires for the components.

PARK, MARKER, AND REAR LICENCE PLATE LAMPS
When the headlamps or parklamps are turned on, CKT 9 (BRN)) distributes voltage from the headlamp switch to the front park lamps, front marker lamps, taillamps, and the rear licence plate lamps. The BLK and BLK/WHT wires are ground wires for the components.

TURN SIGNAL AND HAZARD LAMPS
The turn signal switch is part of the multifunction switch on the steering column. The turn signal lamps and the hazard lamps are the same lamps, and they both utilize the turn/hazard lamp flasher. Turn signal voltage (through the TURN/BU fuse) is only available when the ignition switch is in the START or RUN positions, and the turn signal circuit will only flash the bulbs on the selected side of the vehicle.

[1][2]Turn signal lamp voltage is provided from the TURN/BU fuse through CKT 139 (PNK) to the normally closed contacts of the turn signal switch. The CKT 62 (LT GRN) connects the turn signal switch to the turn/hazard lamp flasher. The turn/hazard lamp flasher continuously opens and closes the circuit until the turn signal switch is moved to the OFF position. Current flows from the flasher through the CKT 16 (PPL) back to the turn signal switch.
- When the turn signal switch is in the left turn position, the voltage is distributed by CKT 14 (LT BLU) to the left front park and turn signal lamps and to the left rear park and the [1][2]turn signal lamp. CKT 14 (LT BLU) also provides voltage to the left turn indicator bulb in the instrument cluster, and the left turn indicator flashes when the exterior turn signal lamps flash.
- When the turn signal is in the right turn position, the voltage is distributed by CKT 15 (DK BLU) to the turn signal in the right front park and turn signal lamps and to the right rear park and [1][2]turn signal lamp. CKT 15 (DK BLU) also provides voltage to the right turn indicator bulb in the instrument cluster, and the right turn indicator flashes when the exterior turn signals lamps flash.
- On vehicles with a single front turn signal bulb, an inline resistor is added to the circuit so that the bulb will draw the same current as in a dual front turn signal arrangement. The current flows through the resistor and is grounded through the opposite turn signal bulb, but sufficient voltage will be dropped through the resistor so that the opposite turn signal bulb will not illuminate.

The HAZARD fuse supplies voltage at all times through CKT 1040 (ORN). When the hazard warning switch is pressed, voltage is available to the turn/hazard lamp flasher through the CKT 1508 (LT BLU). From the flasher, CKT 16 (PPL) returns to the turn signal switch. Voltage is distributed on both CKT 15 (DK BLU) and CKT 14 (LT BLU) to the lamps and indicators. The hazard circuit will flash front and rear bulbs on both sides of the vehicle. The BLK and BLK/WHT wires are ground wires for the components.
