Yes, I too have looked at that diagram on the Hyundai service site. I cannot figure why they would show the layout for the engine fuse box, but not include the table to decypher the fuse locations. They show nothing for the fuse box under the dash. Have you checked the owners manual? Perhaps you don't have that on hand either. You might try finding a replacement fuse box cover at a salvage yard. Some yards don't care to screw around with plastic pieces like this and will give them away if you locate it. The Hyundai service site does list four causes for brakelight problems:
Fuse 16 (10A) blown (which you've dealt with)
Stop lamp switch faulty (ditto)
Wiring or ground faulty
Stop lamp relay faulty
With a cheap multi-meter, you can diagnose a wiring or ground fault by removing the bulbs and checking for voltage between the teminals in the socket and between the positive terminal and the car body while someone presses the brake pedal. If you have no or low voltage across the terminals, but full voltage (~12 to 13+ VDC with a fully charged battery) across the positive terminal/body connection, you have a bad ground wire connection at the back of the car. If no voltage either way, I'd check for voltage at the switch. Perhaps someone else can tell you where to look for the stop lamp relay. If it's not on the fuse box under the car dash, it may be one of the relays integrated on the body control module.
