Help identifying a wiring harness connector in the passenger side door!

Hey everyone, I noticed a rattle in my passenger side door so I decided to investigate. I took off the door card and found that the culprit was a loose wiring connector. I had a feel around but could not find anything to connect it to.

I was wondering if someone could help me identify what it is for? Everything on the door works fine so I'm at a loss as to what it might be for.

Thanks in advance!

Maybe part of the cabling for Burmester speakers? When fitted there are 16 of them somewhere

Can’t think of any other component requirement. Or could be that it’s a standard harness for a range of the group brands and they just use what’s required for individual models.

CAn you confirm the colours of the wires? Brown and any trace? Yellow and blue / grey ??

A light switch in the passenger door handle according to this wiring diagram

It wasn't esay for me to be definitive about the colours based on the picture but I agree the outer handle switch is the most likely.

Maybe for the keyless entry sensor in the door handle.
