Do the tails come in to the back?

Yes. The position where the tails came out of the wall was
a significant influence on the positioning of the CU. I did
move that a couple of inches to make it all line up vertically,
which wasn't difficult on a thermal block wall where you can
almost use your finger nails to scrape out a larger hole.
