Battery Drain - All Fuses Out , still drain

Hi guys,

2010 535xi, all fuses out from the rear and front panel, relays, wire harness plugs and still draining .140 to .280mA where it should be below .50mA.

What else should I do ? My last parts to remove and test would be:
1. DME computer harnesses
2. Starter
3. Alternator

Interesting enough when I pull the positive thick wire from the battery that goes into the rear fuse panel everything goes to 0.00 draw. Is that right ? what does it really mean ?
Where does the other positive wire go ? There is another red wire from the rear fuse panel that goes to the front I believe but I didn't see a way to disconnect it, even after removing that plastic white cover..some of weird screw...

Please help as I am not very familiar with going this car and my first power drain and it`s very bad .. I been delaying this it for too long.
