can it be done? do i just wire the 4 wires to my 4 injector ground wires or will my ecu not work with the box? if this does work, will my stock b series injectors work?

i pretty much understand the benifits from the resistor box just dont know if it will work with my ecu and injectors

 

You only need a resistor box if you are running low impedance injectors.

The ecu has nothing to do with your resistor box.

The ecu sends ground pulses via signal wires to each injector.
The resistor box gets wired into the power wire that runs to each injector....
