Should be a BOSCH ECU, 8v engine.

This diagram shows the injectors in the bottom left and the the ECU in the top right. The wire numbers, plug colours, number of ways and the individual pin connection numbers are shown on the diagram.

Click to enlarge the image, the full image (and many more) can be found in SEDRE, which can sometimes be found (here).

SEDRE also has the diagram that shows the intermediate plugs and sockets for the injectors, which may also be useful to you. Its a very useful bit of software when you actually get it up and running :D

This one shows all the ECU connections and the intermediate plugs and sockets. It includes the injectors, plug colours, number of ways in the plugs, plug and socket pin numbers and wire numbers.

Its just a french translation and then they pick a couple of letters. I don't see any other reference on the diagram and its the pin number and wire numbers that are important.
