Alfa Romeo Spider Cabrio USA speck

[spain]

We have an Alfa Romeo Spider 1983 2.0 injection. Our problem is we are getting no low tension signal to the coil and no spark. It has 2 ECU's, one is jetronic for the fuel injection system and the other one is for the ignition system. Has anybody got the complete electrical circuit diagram for this vehicle? (We have one for the european version but this is totally different to what we require, we do need the american speck system)
This speck for this vehicle was never used on the european models. We would be most grateful for any information and diagrams.
