I had parasitic draw on my 2003 subaru outback legacy h6 llbean 3.0l.

Turned out to be the trailer wiring device in the trunk (unplugged it) and the parasitic draw dropped to basically 0 from .25A

Just letting others know hope it helps battery was dying over the course of 1-2 days

I was wondering if it was a certain brand of brake controller module or something...
