Here are what I believe to be the data sheets for the sensors and injector used on the Magneti Marelli EFI systems. The water air and injector data sheets match, the tps sensor is a car one used on the same family of ECUs so I think the physical size is the only difference. I have hosted them on my own website for now. I have no idea if this is copyright infringement so if it is perhaps one of the mods can delete the links. If it is ok then maybe our webmaster would host them here?
Water temperature sensor
Air temperature sensor
Throttle position sensor
Fuel injector
Hope this helps
