Normal Operation - Except STX
The smart junction box (SJB) provides voltage to the stoplamp switch through circuit 10 (LG/RD). When the brake pedal is applied, the voltage is routed to the high mounted stoplamp and the multifunction switch through circuit 511 (LG). The multifunction switch then routes the voltage to the LH and RH rear lamps through circuits 9 (LG/OG) and 5 (OG/LB), respectively. Ground for the stoplamps is provided through circuit 57 (BK).
