A raw unedited video of how the ECU plug locks in place, and how best to remove it if it's jammed.
It's best to be patient and keep spraying in lubricant instead of getting mad and snapping the locking tab off.
The plug cannot be removed until the white arm is fully extended and locked all the way in at the opposite end, if it's even a millimeter away from fully locked you still won't be able to get it out.
