The boards are plug-n-play.

1. Remove lens;

2. Remove bulb and clean socket; LEDs draw a lot less current and may not break through oxidation on the socket;

3. Place the board frame in the brake cavity with feet out towards the board (it positions the board in place);

4. Loosen the 4 screws so the pins on the pinch clips are flush with the board.

5. Plug the board's pigtail into the socket;

6. Test the running and brake lights to make sure the socket is making good contact; Wiggle the wire; If the LEDs flicker, clean the socket again.

7. Install the board in the cavity; Holding the board with the loose wire grip, work the PCB into the cavity making sure the pinch clips clear the sides of the cavity.

8. Try to seat the outside of the PCB on the outside feet of the board frame until it rests against the board frame

9. Push the inside of the PCB against the inside feet of the board frame.

10. Tighten screws to set the board in place

11. Replace lens.
