Anyway put it all back together and - nothing- car won't start, checked connections again and all seem in place and ok, any ideas what we've done wrong?

Sorted! Don't know what we did but we realised we couldn't hear the fuel pump when we switched the igntion back on, wiggled & pulled relays and fuses, put them back and she started first time.
I took some photos of the ecu and connectors, if it would help anyone thinking of doing this I'll happily put them up but might need guidance as to where on the forum they should be.
Hi Bubs,

I know your post is 2 years old but I have the same car & same problem. Throttle body replaced last year. Pics of ECU would be fantastic.
