Buying a used CEM and fitting

Hi all,

Following on from this thread - thought a new title would be best, for the next person who needs to search for CEM replacement! https://www.volvoforums.org.uk/showthread.php?t=277927

I found the CEM when I was replacing the pollen filter, pulled some fuses and the main connector plug, and can't see any water ingress around these, so really it needs to come out for a good look at the circuits - it's still just the interior lights which aren't working, as far as I can tell. They still come on for a second or two each time the ignition is turned on, before the CEM senses a short and turns them off.

I now have the part number for the CEM, 31314511 AB. Would it be a case of simply plugging this in, and going? I have VIDA so can tweak some settings etc. once plugged in, but would it need properly coding to the car? If it's simple, I might buy it (or a similar one), and if my original can be repaired, keep it as a spare.
