Trim the front of the fender liner around where the bracket of the bumper guard will be (indicated in the picture by the red line). A utility or sharp pocket knife should easily cut through it. It's possible to fold the liner up out of the way and not have to cut it but it's a lot easier to just cut out the small section needed to clear the bracket. With the screws out that we removed in the first step, you can pull the fender liner back out of the way giving you better access to the attachment points for the front bumper guard.
