The park lamps, side marker lamps, and tail lamps are supplied power from 2 different circuits.

When the headlamp switch is in PARK, the park lamps input to the lamp control module (LCM) is grounded. The LCM then applies battery positive voltage (B+) through the IP junction block LP PK L fuse and the LP PK R fuse to the following lamps:

Battery positive voltage (B+) is supplied via CKT 309 (BRN/WHT) to the right park lamps and all of the lamps on the rear compartment lid. Power is supplied via CKT 709 (PPL) to the left park lamps.

Battery positive voltage (B+) is applied at all times from the underhood junction block STOP fuse to the stoplamp/BTSI switch. When you press the brake pedal, battery positive voltage (B+) is supplied via CKT 20 (LT BLU) through the stoplamp/BTSI switch and the rear junction block to the high mount stop lamp and tail/stop lamps.

When the ignition switch is in RUN and the turn signal/hazard switch is in a turn position, battery positive voltage (B+) is applied from the underhood junction block T/SIG fuse through the turn signal/hazard switch to the respective turn signal flasher input. The turn signal flasher receives battery positive voltage (B+) at all times from the underhood junction block HZDT/SG fuse. The turn signal flasher supplies battery positive voltage (B+), in an intermittent on and off pattern, to the respective front turn signal lamps and side marker lamps through the underhood junction block. The turn signal flasher also supplies battery positive voltage (B+) in an intermittent on and off pattern to the respective rear turn signal lamps and rear side marker lamps through the rear junction block. The respective turn signal indicator on the instrument cluster will flash continuously while the turn signal/hazard switch is in the turn position. Battery positive voltage (B+) is supplied via CKT 685 (YEL) to the left turn lamps and via CKT 686 (TAN) to the right turn lamps.

The front side marker lamps are wired with power circuits on both sides. The left front side marker lamp is supplied power by CKT 709 (PPL) and CKT 685 (YEL). The right front side marker lamp is supplied power by CKT 309 (BRN/WHT) and CKT 686 (TAN). When the park lamps are on and a turn is indicated, these side marker lamps flash on and off opposite of the other park/turn lamps. When the turn signal flasher supplies battery positive voltage (B+) to the front side marker lamps, they turn off because the lamp control module (LCM) also supplies battery positive voltage (B+) to the front side marker lamps and there is no net voltage across the lamps. When the turn signal flasher removes battery positive voltage (B+) from the front side marker lamps, they become grounded on that side and light due to the battery positive voltage (B+) supplied by the LCM.

With the turn signal/hazard switch in the HAZARD position, the hazard signal input of the turn signal flasher is grounded. The turn signal flasher supplies battery positive voltage (B+) in an intermittent on and off pattern through CKT 685 (YEL) and CKT 686 (TAN) to all turn signal and side marker lamps. Both turn signal indicators flash on and off continuously while the turn signal/hazard switch is in the HAZARD position.

When the ignition switch is in RUN and the turn signal/hazard switch is in a turn position, battery positive voltage (B+) is applied from the underhood junction block T/SIG fuse through the turn signal/hazard switch to the respective cornering lamp. Battery positive voltage (B+) is supplied via CKT 57 (ORN) to the left cornering lamp and is permanently grounded to G106. Battery positive voltage (B+) is supplied via CKT 58 (BLK) to the right cornering lamp and is permanently grounded to G105. When the turn signal/hazard switch is in a turn position, the corresponding lamp lights.
