Right guys needing some help from the cosworth tech's

I am currently building a sapphire cosworth rep and have a small turbo escort engine and box to fit but am struggling on how to get it running .


I have the original ecu but no one seems to able to make an engine only loom for this

My other option is to convert to weber stuff but not sure how involved this is

Basically I need to know the best way around this

Any help would be much appreciated cheers thanks
