I got nearly everything to work by tracking pin 1 (old connector) to pin 1(new connector). That got central locking working on 3 doors, including drivers - which previously only worked with key, but back door passenger side wouldn't lock. I had 2 connections which both had a brown wire so I switched them and now all doors lock/unlock except drivers door which locks on keyfob but only unlocks with key. I'm leaving well alone for the moment as the key unlock on drivers door is not a problem for the owners (it's what they are used to) but I'm still interested in, eventually, getting the drivers door to unlock on the keyfob. I've asked the owners to note anything that does not work as it should but they are happy with windows/mirrors/lock and unlock all ( apart from drivers door) working now. We don't know it's a pre facelift or not and it looks very similar to my own Fabia from 2011 so possibly pre facelift. Thanks for the quick response.
