Quistor

I need to wire one of these up for an engine swap. I assume that the 4 red/black wires are to go to the injectors and the other wire is power. My question is does it matter which red/black wire goes to which injector? or can you just wire any one to any injector. Also where does the power wire that goes into the Resistor itself come from? Can i splice into a wire for the power and what color wire would that be?


Thanks
