Ca18et With Sr20det Swap

hello,
I've put a japanese s14 sr20det engine in my european '88 s12 ca18et.
I've tried and I've tried to find the right wireing diagram, but it seems that there are so many different ones..
So I decided to buy an engine management system.
the engine is pretty much stock, except for the intercooler, blow-of valve and exhaust.
I just want the car to work again..
Hope someone can help me!

I've moved your topic to SR20DE/DET, thats where it belongs.  

Only other issue is, you may want to post on the UK forum, as the wiring between US and UK/Europe models is very different.
