I've figured out how to remove the Interior Dome Light connector.
https://imgur.com/a/6C8OBeQYou need:
* A Dashboard trim removal tool (DTRT)
* 2mm/3mm wide flat head screw driver (FHSD)
Before we begin, remove light cover and light bracket. Easy.
Next we try to remove the connector.
The connector is attached to the car body using 4 push clips (not sure if this is the correct terminology).
This is very hard to remove directly by hand.
[*] Wedge DTRT between car rib* and connector. Just place it there. Don't exert force.
[*] Use FHSD, push in the clip closest to you
[*] While clip is pushed, lift the connector out of the socket using the DTRT
[*] You will see that the connector is now unseated on one side
[*] Once one side is unseated, let go of the FHSD
[*] Hold the DTRT in place, making sure the unseated side does not slip back into the socket
[*] Next, use the FHSD to push in on the clip on the right (more convenient than left)
[*] The force you exert on the right, causes both the left and right clip to move in
[*] Use this advantage to apply more force on the FHSD to pry the connector out. It won't come out straight away.
[*] You will find that the clip furthest to you will be the most stubborn (Because you can't access it directly)
[*] Apply a bit more force on the DTRT and the connector will come out

**Note**
Once connector is removed out of its socket, do not pull on connector. There does not seem to be any slack on the wires leading to the connector.
