How to Install Raxiom Smoked LED Sequential Corner Marker Turn Signals (15-17 All) on your Ford Mustang

1. Using a plastic trim removal tool, remove the two plastic rivets holding the fender liner in place in the wheel well on both sides of the vehicle.

2. Remove the belly pan from underneath the vehicle. To do so, remove the 12 7mm screws on the outside edge, four 7mm screws on the belly pan itself, and six plas­tic rivets on the outside edge to remove the belly pan.

3. Looking at the fog light bezel, unplug the factory turn signal, side­marker, and fog light connectors by depressing and pulling straight back. Then remove the six 7mm screws holding the fog light bezel in place.

4. Press outward on the tabs holding the fog light bezel in place to separate it from the bumper. Once the bezel has been removed, take it to a working area with a soft surface.

5. Remove the three 7mm screws holding the turn signal housing to the fog light bezel. Next, remove the turn signal housing from the bezel.

6. Remove the sidemarker socket from the factory turn signal housing and remove the bulb. The socket will be used with your new turn signal housing.

7. Using the switch on your Sequential LED Turn Signal, set your desired turn signal blink rate.

* US-Sequential turn signal rate that  matches the USDM tail lights  

* EU-Faster sequential turn signal rate

* Off-Static, non-sequential turn signal

8. Once the blink rate has been set, insert the switch into the factory sidemarker socket. Reinstall the socket back into your new turn signal housing. 

9. Install the new turn signal hous­ing into the fog light bezel, reinstall­ing the three 7mm screws.

10. Reinstall the fog light bezel in the bumper, ensuring the tabs snap into place. Replace the original six screws to secure the bezel. 

11. Plug the connector on the turn signal housing into the factory turn signal connector. Then reconnect the sidemarker and fog light con­nectors.
