Well disregard my question. I downloaded the Service Manual, found where all the switches, plugs, and wires were. I then disconnected and reconnected them all as well as removed each fuse (one at a time) and reseated them.
Tried the brakes, and now they work! I must have had a loose connection somewhere, but it sure wasn't obvious when I disconnected each one. All connections felt secure before I disconnected them. Go figure.
