For more detail about this product, please visit Chevrolet Silverado 1500/GMC Sierra 1500 Behind-The-Grille LED Light Bar (35-958).
Step 1: Prepare the LED Light Bar
Step 2: Unscrew the Grille
There are 2 ways you can deal with the grille: you can either carefully pry out the grille to give you enough space to insert your LED light bar through the gap, or remove the grille entirely. We discovered that the grille of our tested GMC Sierra 1500 has some give and the spacing to install our LED light bar without removing the grille. However this may be impossible to perform for other trims or models such as the Chevrolet Silverado 1500 for which our LED light bar is also compatible with. Additionally, you may risk scratching your LED light bar and breaking parts of the grille.
Step 3: Fully remove the grille. For some trims and models, the grille does not give your hand the clearance to reach through them. Follow these steps if this case applies to you.
Step 4: If you choose not to remove the grille, you can pry open the grille to give you enough space to slide in your LED light bar. Do this only if your car allows for it.
Step 5: Install the exclusively designed LED lightbar mounting brackets
Step 6: Install the LED light bar
Step 7: Connect the LED light bar to an existing harness/12V power source or install a relay and switch.
Step 8: Test all of your lights to make sure everything functions. If so, refasten all the screws and clips you removed to finish installation. You can now enjoy your GMC’s new LED light bar!
