Someone on a Honda forum pointed me to a more complete manual for my Honda Accord, which actually contained information about the interior wiring and fuse #13.
I did some editing. The area I highlighted in yellow is where I believe the problem lies. The items circled in red I have confirmed are not receiving power, while the items circled in blue are confirmed to be working. I forgot to add that the safety indicator in my car does not show when any of the doors/trunk are ajar. Now I still need to physically locate where the wires all meet and go from there.
