12 volts are supplied from the BEC fuse 10 (30A) to the accessory delay relay 1 on circuit 296 (WH/VT). When energized by the SJB, the accessory delay relay 1 then supplies 12 volts to the quarter window switch on circuit 194 (PK). When the quarter window switch is pressed in the OPEN position, 12 volts are supplied to RH and LH quarter window motors on circuit 882 (BN/YE). Ground is supplied on circuit 881 (BN), through the quarter window switch, then on circuit 1205 (BK). When the quarter window switch is pressed in the CLOSE position, 12 volts are supplied to the RH and LH quarter window motors on circuit 881 (BN). Ground is supplied on circuit 882 (BN/YE), through the quarter window switch, then on circuit 1205 (BK).
