I have three Alfetta 1.8 wiring diagrams. The model type numbers are;
113.12
116.42
117.17
Although the above listed diagrams are early 1980s versions, I think that they would be closer to your Alfetta than the 1975 USA version with Spica fuel injection that was the subject of this thread. The model type number should be on a metal plate riveted to the left side of the bulkhead.
