In the first picture, the black cap thing that goes into the headlight assembly through the engine bay, do you know whats that called? I need a replacement, i made the hole a bit to big, do you know where i could get it and how much it would cost? Thanks! and btw, ddm is either good or bad, the 4 times i ordered them for 4 different cars, only 1 failed but it was cheap so oh well. lol
