I had to behead my fully working Addams Family to get it in a Nissan Note to transport it to my new house.
I took loads of photos before I unplugged.
Unfortunately when it was put back together, although it first looked fine, there are the following issues.

Column 3 and row 3 lamps are not working.
Yellow string of backglass GI is out.
Ramp diverter not working.
Centre left jet bumper not working.
Bookcase motor doesn't work.

I've rechecked all the connections and everything looks as before.
Any advice on what may be the cause of these would be greatly received.

Thanks for the advice will check out the D2 data line and recheck all the connectors.

I ended up pulling the power board to test the components. All checked out fine.
Re-plugged everything and we are back up and running.
Suspect there's still a wire that may give me grief if I unplug in the future!
Found the spring connecting the diverter had broken so once that is fixed everything will be fine.
Thanks all who offered advice.
