Toyota Repair: brake lights dont light., toyota camrys, brake light switch

Question
My Moms 85' toyota camrys stop lights dont work. All fuses are fine and the fuse box is fine too. Somewhere from the front fuse box to the rear end of the car is the problem because there is no fire in the rear end. Do I need a wiring diagram? If so, where can I find it? Or, what else could be the problem. Behind the brake pedal is another kind of  box I have no info. on it though. Which of those  wires would pertain to the rear end stop lights? All other lights work except the stop lights.

Answer
Look for the brake light switch under the dash, it should be mounted on a bracket, there is another bracket on the brake pedal that makes contact with the switch and pushes the plunger on the switch in/out to turn the brake lights on/off, there are two wires on the switch, one has 12 volts all the time and the other one should have 12 volts with the brake pedal depressed, if not then replace the switch.
