Battery drains overnight on BCM

What is your question?

I have found one factor that radio cause battery to drain. So I disconnected and removed the radio to continue the Parasitic test. The amps reads from 0.74 A down to 0.44 A. It's still a lot. Now, amp reads at down to 0.013 A when I disconnected pink connector of BCM. I want to know the wire information to which BCM pink connector connects. Any idea would be helpful and appreciate!

IF you are really down to 0.013 amps , then you should not have a dead battery due to a 'parasitic draw'. 500 milliamps (0.05A) or below is within the 'normal range for most cars , after all modules have 'gone to sleep'. How old is the battery? Do you have a tester that can test for a 'bad cell'? Are you familiar with the varied symptoms that a bad cell can display? Again , IF you are truly at 0.013A, I would look elsewhere for the starting problem. OOORRRR , I could be totally off-base and some one else will let me know. Good luck!--- also forgot to ask--how much time are you allowing , for all modules to go to 'sleep' before draw testing?

Thank you for your answer! You seem missed the point that I have to disconnect the pink connector of BCM to make amp reads at 0.0.13a . To figure it out, I have to know what parts in the vehicle are connected to BCM via this Pink connector. That's why I am asking if anyone who has the wire information or similar experience is willing to share. The car accessories connect to these wire by google searching. Still working on it in the lazy mood. I don't need this car for rush. But It will be a lot of fun if I could clear the issue with help here. ;)
