Thanks for lending a hand, Fuse.

As it turns out, fuse 13 was blown. I had a spare, but it blew nicely the moment it made contact. Ignition off at the time, btw.

I went ahead and carried out the remainder of the tests:

Fuse 12 = hot always
Fuse 13 = hot always (but on the opposite post as 12 if that matters)
Fuse 9 = hot in on or start

Thanks!
