Battery Drain on a 07 Cobalt

HI Im new to this ,I just got a 07 Cobalt with a 2.2. And there is a bad drain on the battery, New battery, 5 amp drain , I all ready pulled the fuse's one at a time and got no change. The only way it changes is if i pull the 50 amp fuse in the trunk,and disconnect the the 2 positive cables off the jumper post under the hood at fuse box, and if i hook either one back up the 5 amp drain comes back
any help would be greatly appreciated

The 50 amp fuse B+ in the trunk goes to the BCM. The 2 wires on the boost post are one from the battery positive terminal and the other goes to the starter.
