Still confused lol.
I just watch the video on the three fuse boxes within the crossfire and when he got to the very last one that’s on the passenger side he pointed to a very large box and then open the contents and it doesn’t look anything like my area that I missing a lid for.
Right next to the large box that he said was the third fuse there’s a small square box but he never said anything about but that’s what I missing the lid for.

I took a screenshot of the last moment of the video and take a look to the right of the fuse box that he describes is a little square black box. That is the piece in question for me.
