witch fiesta from the 80's

I am looking for wireing diagrams/schematics for a fiesta. roughly from late 1980's

I know this may sound strange but...I have a ECU and i need to find out how it was orignally installed in the fiesta.

I have managed to salvage the following information, of the Internet. fiesta 1,1 and 1,3 HCS ( DIS / ESC ) version's of the fiesta the ECU it only for ignition not EFI. ecu label : Motorcraft

I have a haynes manual for a escort , where there is a clear picture of this exact ECU, but it is not in the electrical diagrams :-( I have also managed to get hold of a fiesta service manual , but is it in russian :-/

any info or help would be apprieciated
