Forget that! 750 Paso have very bad quality Lucas start solenoid and 907IE have much better one made by Hitachi(yes, its from Japan...) and that Hitachi unit was quite cheap from Ducati dealer. Ducati have used that Hitachi unit very long time in very many modells,.... i think in all modells! I have changed just that unit to my 750 Paso many years ago and still function very well, what never happen with Lucas unit. It was "stucked" very often and didnt start, like should...
Btw, those connetors are different in those units, so think that, before You cut Your wires!!! :thumbup:
