Fuel injectors are designed to atomize fuel that is sprayed into the combustion chambers. The injectors are controlled electronically by the engine control module, which communicates signals to open the injectors using a fuel injection wiring harness. This harness is made up of a number of wires that carry electrical signals to and from the fuel injectors, allowing the control module to recognize potential injector faults and keep the engine running at peak performance and efficiency.
