 . Press-fit the socket into its slot and check that wires are still connected to the socket with a multimeter.  If everything’s ok, pour a fair amount of hot glue to fix it in place.
+To make the installation easier:
+- Make sure the pins and cables are bent rather flat, so that you have the clearance to slide the socket to its place from the inside.
+- Use a screwdriver or similar to apply force and push the socket thru the opening, in the end.
+- Applying the hot glue might get tricky, as the crevice is small, use of a tool might be a good idea.
