Tbi to multi port injector questions

Ok I'm about to splice my new ev1 plugs in to my tbi harness and question 1 is on the tbi wiring diagram it has power on one side or the injector and the other goes to the ecm so is the ecm side the ground?
Question 2 is what side of the ev1 plug is pos. and neg. or does it matter?

Yes, ECM provides ground to fire the injectors.

As for injector polarity, holding the injector upright, inlet at top, nozzle pointing down, looking into the connector: the left side terminal is power (+).
