There's a tool in most parts stores that is invaluable for battery drain issues, Its called a parasitic draw test adapter. Some marine stores use it to isolate the battery in boats for long term storage. Use it with a DVOM (set for DC amps). Put on the adapter, set your DVOM to measure from the battery post to the other side of the adapter, then open the adapter. The reading you get is the draw on the battery. Be aware that some vehicles can take up to 10 minutes for the modules to power down. You're looking for about 25 milliamps max draw. Start pulling fuses until the draw gets to acceptable levels.
