Parasitic battery drain, but...

I've had this problem for over the past month or so, and I've just been pulling fuse #7 to stop the drain. I've read into a lot of forums and discussions on this matter and so I proceeded on removing the panels from the lift gate and I pulled the two latch plugs and the rear wiper motor plug, and waited a few minutes and my test light never showed any sign of change. I proceeded to just pull every plug on the lift gate to see if that might help, but no, it still did not.

Before moving on to check the BCM, I went and checked the factory power amplifier and no change. Went up to the dash, pulled the security light/auto headlight sensor, and no change. Next I pulled the instrument cluster out and, surprise, no change.

Finally, I went and pulled the black plug first, waited, and no change, then finally, I pulled the white plug and the test light, within a couple of seconds, went out, and the light turned back on with much less power.

I found a picture on what all the pins connect to, but I don't have the time to go and pull pins one by one to figure it out, if anyone has any ideas on what it could be, it would be much appreciated.
