The smart junction box (SJB) provides voltage to the indicator flasher relay through circuit CBP20 (YE/VT). The indicator flasher relay routes the voltage to the multifunction switch through circuit CLS42 (VT/BN). When the multifunction switch is placed in the LH or RH TURN position, the multifunction switch routes the voltage to the LH or RH front turn lamps through circuits CLS41 (GY/YE) and CLS39 (VT/WH), respectively. The multifunction switch also routes the voltage to the LH or RH rear lamps through the existing stoplamp circuitry. Ground for the indicator flasher relay is provided through circuit GD161 (BK/YE).
