Battery drain help! I have the causes

I have a 2007 mercedes benz e63 amg vin [size=16px]WDBUF77X07B009046 . [/size]Battery drain help. Car dies in like 3 days if I don't turn it on. I installed an upgraded alternator still no fix installed a odyssey red top battery still same. did all 3 parasite drain test and while having a multimeter in sequence on negative terminal on milliamp I got 2.92mA. Disconnected every fuse and relay and no drop. Then did it on 10 Amps and also stayed the same. Finally tried to read the mV on each fuse and was able to find the culprits.

rear truck left fuse box
fuse # 9 (25 fuse) .2mV pulling while car is off

Interior driver side fuse box
Fuse # 29 (7.5 fuse) 1.4 mV pulling while car is off
fuse #37 (5 fuse) 1.9 mV pulling while car is off

Then everything else was 0.0

What should I do next (already ordered the overhead module from ebay so hopefully will fix #9 issue) waiting for delivery

Start here, it's for the E55 but may point you in the correct direction; otherwise get into WIS and pull the schematic;
