Brake Light Switch Removal & Installation 1. Lift the locking tab on the switch connector and disconnect the wiring. 2. Remove the hairpin retainer, slide the stop lamp switch, pushrod and nylon washer off the pedal. Remove the washer, then the switch by sliding it up or down. > On trucks equipped with speed control, the spacer washer is replaced by the dump valve adapter washer. 3. To install the switch, position it so that the U-shaped side is nearest the pedal and directly over/under the pin. 4. Slide the switch up or down, trapping the master cylinder pushrod and bushing between the switch side plates. 5. Push the switch and pushrod assembly firmly towards the brake pedal arm. Assemble the outside white plastic washer to the pin and install the hairpin retainer. *** CAUTION*** Don't substitute any other type of retainer. Use only the Ford specified hairpin retainer. 6. Assemble the connector on the switch. 7. Check stop lamp operation. *** CAUTION*** Make sure that the stop lamp switch wiring has sufficient travel during a full pedal stroke!
The brake light switch is connected to the brake pedal and the brake linkage under the dash with a single bolt.
