From what I found out mainly here on forums EEC IV Escort Cossie schould connect to FDS2000 diagostic equipment Ford dealerships have. Friend of mine took it there, they even found out the 3 pin diagostic socket for which they have a plug in their system. They found Escort Cosworth on the diagnostic program but they wouldn't comunicate. Are there any more things I schould know? Some info out of engine ECU would be usefull for maitenance and setup.
