My battery's being drained of 1.9 amps with everything off. Despite disconnecting all fuses, relays and bunch of individual components, all I've found so far is that it stops when I disconnect plug E19 in the pic below. Unfortunately this is a 'battery' connection so not real helpful. I'm just trying to narrow it down some more, I can't really tell by the diagrams whether this goes into the cabin and/or to all these components in the pic. Any ideas?
