Pertronics ballast resistor removal question

I installed a pertronics 2 on a slant 6. There are two blue wires in one plug on one side of the ballast resistor and two brown wires in one plug on the other side of the ballast resistor. When removing the ballast resistor for the pertronics unit do both brown wires get connected to both blue wires or does one of the blue wires and one of the brown wires stay connected to the ballast resistor for something else?
