What does this round blue plug in my Drivers side door go to ?

[MidwesternTexan]

I had the 'Door Ajar' light often/always on.
I watched a YOuTube about this year, the wires in the door loom were too short and break.
If you have never found the fix. I can just about guarantee, inside that flexible rubber cover for the wires, is at least one broken wire!


I took it all apart, sure enough! The large black ground for nearly everything in the door, and another wire.
I'm fixing/slicing that- no problem.

What the hell is this round blue plug go to that was in the door, up near the top/rear of the door?
I can't find anywhere it would go to. Is it extra?

If you watch that video you attached (at 10:55 in the video) you will see that connector. It is a junction that runs to the door latch switch. It may be where the keyless entry push button control ties in to the circuit (I am not sure).

Thank you! I see it now!
Too Bad it's already back together! Quick fix if I need to hook it back up- I'm going out to check it now! The keyless entry was working before.

AND

I FIXED the 'Door Ajar' light!! I didn't bother with checking the switch like he did, or lubing it.
I went right at the wire loom like he shows in the door jam.
Sure enough, 2 wires broke, including the large common black ground. Spliced some wire in, viola!
It's so nice doing things yourself. Thank God for that video, I NEVER would have looked there!!
I hope others with the 'door ajar light are seeing this!

* UPDATE*

Funny, I didn't take the blue plug off when I was getting into the door!

Everything still works! The Key Fob, The keyless entry, etc.

** I figured out what it does!
It locks all, or unlocks all when you manually put the key in the door! That's it.
Not worth going back in for that.
I just put it on CL, 4x4 ELT, 104K miles, 4.6 V8 2003Explorer XLT.
