A four wire harness connects the fuel injectors to the ECM. The RED wire is at

12 volts and connects to all injectors. The BLUE, YELLOW and WHITE wires

each go to a pair of injectors and are normally at 12 volts for a zero

differential. To fire the injectors this voltage is brought down to near ground

creating a potential across the injectors.
