does it matter which ground for injector plugs?

[compression]

When putting on new plugs for my injectors, 2/3 broke off when removing my harness i didnt note which color wires went to which injector, from what i understand it doesnt matter being as it goes straight into the resistor box. I assume the darker wire is ground, may of may not be . but i have the ecu pinout so the lighter color wires i have covered.

Anyways! thanks in advance!

The ground side actually goes to the ecu. The resistor pack side is the power supply for the injector. The injector plug will have constant power and the ecu grounds the wire to fire the injector. Each injector has to have the right ground wire going to it from the ecu or else they won't fire at the right time.

Ah ok, well then i have the ground wires correct, its just The power, does it matter which goes where, they all go to the resistor box right?

No it won't matter on those, they are all connected together anyways.
