i had aftermarket peak and hold injectors previously installed on my car. four (4) yellow/black wires were snipped and wired into the box. well i sold the injectors and took off the resistor box. i was wondering when rewiring the yellow/black wires, if it matters which wires were matched up. or can i just rewire them together randomly, since they're all the same color.

 

It doesn't matter which wire goes to which.

I've thought about this, and decided instead of just directly soldering my resistor box in, I'm going to solder some plugs in place so that I can simply remove the resistor box and plug the harness back together if I ever want to go back to saturated injectors.
