Fuel injector sequence

[sierra3dr]

Ok fellas (and ladies),I hope everyone is ok. I've been doing some work on my DOHC (N9 engine) where I've took the engine out. As we know that means disconnecting all connectors from all sensors,and injectors. Question is,is imperative to have the correct injector loom plug connected to the correct injector? For example, mistakenly putting connector that was originally on cylinder 3 injector onto injector 4?
Thanks in advance

Yes it is imperative you get the correct plug back on the correct injector. If not the car will not run properly because fuel will be spraying at the wrong time.

thanks Stealthee. I always thought they inject on and off rapidly,as we know as pulse width,regardless when the intake valve is open or not
