Wow! Thank you so much for the explanation and the pictures!
I did look into getting those exact items from Amazon. It seems pretty straight forward.
I believe the fuse number you taped into is fuse #54 (also found another thread where you called it out).
According to this fuse diagram, fuse #54 looks to be the fuse for the 12V sockets, so this falls in line with what you described.
Tucking the wires underneath the trim is the easiest part in this installation.
Fuse box looks a little tough to get into. Might help to use a long needle-nose pliers.
Thanks for sharing the information. I feel confident enough to complete the install!
Edit: It also looks like regular fuses (not the mini's).
