The long piece of plastic sitting across the frunk is the trim piece I removed. In the picture it is turned upside down. The now uncovered front area of the frunk is where the trim is usually installed. There are five clips equally spaced on the underside of the trim that hold the trim onto the body area plus two tabs that slip underneath the adjacent trim that runs up the sides of the frunk. The long foam rectangles would be inward (closest to the storage area) and the arches would be over the headlights. Basically you can imagine grabbing the trim by the most inward edge and flipping it over to insert it back into place.No idea what I am looking at here. Need a better explanation/guidance!
