Before you remove the doors and start drilling holes, consider this approach.
Stick your hand to the hole with the wires, and push the top of the connector out. (press the locking tab from the inside)
Now use one of these, with a T20 bit. To remove screw in bottom of connector.
My car is currently on the lift, so I have very limited access to the connector (can’t open the door all the way). so the next pictures are showing the driver side, which should be the same.
Once the screw is removed, you will be able to pull the connector out.
Disconnect the two sides of the connector by pulling tab (like the German style sliding tab)
Look at two sides of the connector.
Yellow arrow shows open space. Red arrow shows white plug that is not in use.
You can remove the white plug and channel the wires thru this space.
If you will do that, you can pass the wires to the door thru the original grommet, and you will be able to put everything back in place
Just don’t forget to leave enough spare wire inside the car, in case this connector will have to be disconnected in the future.
Good luck
