Looking at the pictures of your CCCU, I would remove it from the car and carefully check all the pins for damage and corrosion. It may have even been wet at some stage, so internal corrosion could be possible. Give it a good clean and scrub up then retry. Failing that your best bet would be to liase with Tom @timmus about him waving his magic wand over a second hand unit and all the other things you need to do when swapping a CCCU over.
Yes it was really grotty in there so I spent all of yesterday stripping and cleaning all the contacts, making sure there was no corrosion and furring when it went back together.
On some of the multiplugs it did necessitate removing the pins from the plugs and cleaning them that way, they were all green and furry so I was worried about high resistance
