Update from my previous post. I install the TOF connector in the centered location and fully attach the screws (including the one that secures the TOF ribbon cable). There is no short, the drone start normally, and I get 4 cameras on VOXL portal, but no TOF. Also voxl-camera-server -l only see 4 cameras. So TOF connection is definitely Ok, but sensor not present.
