Resistor box wiring.. Help!

[Sc3002]

I need to wire in a resister box. I have the box and the injectors. My question is, everything I know and read shows the box wired in to the 12v side of the circuit. Leaving the ecu ground circuit alone. However the EMU diagram shows to leave the 12v side alone and wire resistors to the ground side from the EMU to the injectors. Backwards from where it's usually wired. Can someone help me out here please?

It doesn't matter!

So long as it's on there, doesn't matter what side of the circuit. I tend to use 12v myself though.

I'll take all the power wires, and cut it where they split (or join them all together, whichever is easier), then resistor goes in place, and the six wires out, goes to the injectors
