Well it's all running and driving finally!!
Had the day off yesterday so set about it on my own and got it all done by 4ish. Took it for a quick drive, shower then stuck with the Mrs all night lol
Covered about 100 miles in it today and all feels well, EML came on but fault indicates 2nd lambda so it must be because of the decat.
I'll get some pictures up when I've thrown a bucket of water over it.
