Normal Operation - Freestyle and Five Hundred
When the brake pedal is applied, the stoplamp switch routes voltage to the smart junction box (SJB) through circuit 810 (RD/LG). The SJB then sends voltage through circuits 1363 (WH/RD), 1365 (GY/LB) and 1374 (TN/LB) to the LH stoplamp, RH stoplamp and high mounted stoplamp, respectively. Ground for the stoplamps is supplied through circuit 1205 (BK).

Normal Operation - Montego
When the brake pedal is applied, the stoplamp switch routes voltage to the SJB through circuit 810 (RD/LG). The SJB then sends voltage to the stoplamps through circuit 1374 (TN/LB). Ground for the stoplamps is supplied through circuit 1205 (BK).
