All the ones that protect circuits that work when the key is off...
Brake lights, courtesy lights, etc. Quite a few.

Re: finding battery drain
Headlight switch wires behind the dash had melted together on mine. If Those suspects don't work, narrow it down to high voltage components that are hot with engine off, and trace the wiring through a little and see if you notice anything suspicious.

Re: finding battery drain
disconnect battery cable and put multimeter between cable and post. then watch reading as you pull fuses when voltage drops then you know where your problem is.
