Get inside the car with a multimeter and have someone pull fuses and and put them back in one by one. You will know which curcuit the drain is on. Do a search, i believe this has been covered before.

Such a tried and true method that I have used more times than I can count.

Once you find the golden fuse, the real search starts. Find the best electrical schematic you can and chase down everything serviced by that one golden fuse.

I have had some problems with other manufacturer's schematics not being accurate enough. In other words, crap was drawing power from the wrong fuse as listed in the diagram! Tell me if that wouldn't get your goat!
