This is a tutorial on how to install the 20" 54W high powered LED light bar behind the grille of a 2015 and later Ford Mustang (35-977). Please note that if your Mustang is the Ecoboost model, it has active grille shutters that must be removed in order to mount the LED light bar. If your Mustang model is either the GT or the convertible trim, you may ignore this note; neither has active grille shutters.
If you are installing this LED light bar onto the Ecoboost trim, we highly recommend removing the bumper first before taking out the active grille shutters and reinstalling the bumper once you've mounted the LED light bar for a more streamlined installation process. You may also remove the bumper if you do not have active grille shutters. Read on to learn how to remove your Mustang's front bumper.
Step 1: Secure the rear side grille mesh mounting brackets onto the LED light bar. Use washers on both sides of each bracket.
Step 2: Check to see if your car has active grille shutters. You'll be able to tell by looking through the mesh grille.

Without grille shutters:
Step 3: Undo the fasteners to remove the engine shield and reveal your working area.
Again, if you are working with an Ecoboost model, remove your bumper before taking out the active grille shutters. To learn how to remove your Ford Mustang's front bumper, watch the video tutorial below:
Step 4: If you did not remove your bumper, insert the LED light bar through the radiator space.
Set the ultra slim LED light bar below the horse emblem and secure it to your mesh grille using the included front side mesh mounting brackets, hex screws, and nuts.
Step 5: Wire the 20" LED light bar using the relay wiring harness with switch.
Step 6: Test the 54W LED light bar to make sure it lights up properly. Once you've confirmed full functionality, put the engine shield and bumper (if applicable) back on to finish.
You may now enjoy your Ford Mustang's brand new behind-the-grille mounted ultra slim LED light bar!
