I own a Tesla Model S 90D and the fuse box shown here is different than the one I have in the Frunk.

Newer Teslas do not have the accessory port fuse in this box. Instead, the fuse is in a box located just inside the right side footwell, up against the outside of the car. https://www.youtube.com/watch?v=jgaXStUt... is the best documentation I have; next time I will photograph steps and create a guide here.

You may want to be more specific with the vehicle description as this doesn't apply to later Model S. My 2016 facelift is completely different. There's another fuse block on the passenger side kick panel that house the the majority of the interior 12v leads.
