Normal Operation
When the brake pedal is applied, the stoplamp switch allows voltage to flow through circuit 511 (LG). Circuit 511 (LG) provides voltage to the high
mounted stoplamp and the smart junction box (SJB). The SJB then provides voltage to the LH and RH rear lamps through circuits 22 (LB/BK) and
810 (RD/LG), respectively. All the stoplamp are provided ground through circuit 57 (BK).
