Well.
Back from Portsmouth. Have made purchase.
The guy was really nice. HE suggested we see if it plugs in first. Nice of him.
HE took out my old one and plugged it in - all good. How nice is that? Car didn't start though but that's because it's not mapped I guess.
Soooo.. all set up now. Just need some kind soul to do the work - yeah - you know who you are....

Thanks for everyone's help - Dyney and Jaffa especially.
