The P75 diagram is practically identical with the 1.1 SPI one, only that in P75 there is no connection to pin 26 of the ECU, so this one you have to get rid of, and there are four injectors instead of one. The diagram that Honeymonster quoted has at least the pin to the dash Injector Light missing, which is, from the top of my head, pin 6. And pin 7 (again, quoting from head) goes to the immo box, if you have/want one.
EDIT: attached what I have, but I cannot guarantee that there are no errors on this one either.
