Normal Operation
The BEC fuse 10 (30A) supplies 12 volts to the accessory delay relay 1 on circuit 296 (WH/VT). When energized by the smart junction box (SJB), the accessory delay relay 1 supplies 12 volts to the LH front window control switch and the RH front window control switch on circuit 170 (RD/LB).

When the RH front window control switch (on the LH window control switch) is pressed in the up position, the LH front window control switch directs 12 volts to the RH front window control switch on circuit 313 (WH/YE) which then directs 12 volts to the RH front window motor on circuit 1506 (RD/WH). Ground is supplied on circuit 1505 (YE/RD) through the RH front window control switch then on circuit 314 (TN/LB) to the LH front window control switch which is grounded through circuit 1205 (BK). When the RH front window control switch (on the LH front window control switch) is pressed in the down position, the LH front window control switch will direct 12 volts to the RH front window control switch on circuit 314 (TN/LB) which then directs 12 volts to the RH front window motor on circuit 1505 (YE/RD). Ground is supplied on circuit 1506 (RD/WH) through the RH front window control switch then on circuit 313 (WH/YE) to the LH front window control switch which is grounded through circuit 1205 (BK).

When the RH front window control switch (on the RH side) is pressed in the up position, 12 volts are supplied to the RH front window motor on circuit 1506 (RD/WH). Ground is supplied on circuit 1505 (YE/RD) through the RH front window control switch, then on circuit 314 (TN/LB) to the LH front window control switch which is grounded through circuit 1205 (BK). When the RH front window control switch (on the RH side) is pressed in the down position, 12 volts are supplied to the RH front window motor on circuit 1505 (YE/RD). Ground is supplied on circuit 1506 (RD/WH) through the RH front window control switch, then on circuit 313 (WH/YE) to the LH front window control switch, which is grounded through circuit 1205 (BK).
