This installation guides applies for 76-366 2024 Ford Mustang LED Side Markers
Step 1) Open the wheelbase cover to access to the back of the side markers.
Step 2) Disconnect the OEM harness and utilize a plastic trim removal tool to carefully extract the factory-installed side markers.
Step 3) Please inspect the back of the LED side markers for the "L" or "R" markings, as the 2024+ Mustang uses identical side marker shapes for both the front and rear, making it critical to determine the correct fitment.
The marker labeled "L" will fit either the driver side rear or the passenger side front depending on the color.
The marker labeled "R" has its pins inside the adapter slightly adjusted, and it will fit either the passenger side rear or the driver side front depending on the color.
