Fig. Fig. 1: The brake light switch is retained to the bracket with a locknut

To install:
  1. Install the new switch and install the locknut, tightening it just snug.
  2.  
  3. Reposition the brake light switch so that the distance between the outer case of the switch and the pedal is 0.02-0.04 in. (0.5-1.0mm). Note that the switch plunger must press against the pedal to keep the brake lights off. As the pedal moves away from the switch, the plunger extends and closes the switch, which turns on the stop lights.
  4.  
  5. Hold the switch in the correct position and tighten the locknut.
  6.  
  7. Connect the wiring to the switch.
  8.  
  9. Check the operation of the switch. Turn the ignition key to the ON position but do not start the engine. Have an assistant observe the brake lights at the rear of the vehicle while you push on the brake pedal. The lights should come on just as the brake pedal passes the point of free play.
  10.  
  11. Adjust the brake light switch as necessary. The small amount of free play in the pedal should not trigger the brake lights; if the switch is set incorrectly, the brake lights will flicker due to pedal vibration on road bumps.
