Part is held on by several (6?) push clips and has tabs which lock into the bumper on the parts leading edge. Part number is the number on the left of the highlight in blue:
11 is the black centre grille section and won't need to come off. Looking at my EC there are just the 6 scrivets the need to be removed. The part actually fits OVER the black section at the top edge rather than under like I first noted (what I marked as tabs are actually the flutes in the fascia plastic - my bad). I am unable to do a test removal as I have a nudge bar with LED light bar attached over the top and it's a pain to remove just to test.On the second image, do you know if part 11 needs removing. I'm thinking part 11 will need to be off to install clip 12 behind?
