Plan out your installation. Look at your car before removing anything and see where to mount the strips. Ideally the grille strips should be mounted behind the bumper and not be visible while on or off.
Next, remove the bumper and mount the strips. They come with 3m tape and can be installed that way, just make sure to use adhesive promoter and to clean the area well before mounting. It is suggested to add additional zip ties for extra security.
After all strips are secured, run all the wires to your controller and secure that to your mounting location.
Once completed wire up your controller to your power source and test all strips. If all is working, reinstall your bumper and enjoy!
