How to disconnect Door Wiring harness?

[CrossTrek]

Hello!

I'm having some troubles with the audio and central lock on the driver side door. 3 months ago my door central lock left work when i press the button on the key or when i pull the lock. After a long seaching i realiced that if i press or move the wires that cross between the door and the cabin the central lock works...
Today the audio of the door started to fail so i tought that the wires are cut down too.
I took some photos, and thats it.. the wires are cuted, so i intented disconnect the harness but i couldn't.

Somebody had the same problem and know how to disconnect that conector?





Cheers!
