The electronic control module (ECM) controls the injector solenoids through the SIGNAL and RETURN wires in the engine harness. The wires run from the fuel control module to a 15-pin connector located in the rocker lever housing. The 15-pin connector connects the external engine harness to the internal actuator harness. The internal actuator harness contains a SIGNAL and RETURN wire for each of the six injectors. There is also a connector on the internal actuator harness that connects to the engine brake harness.

Refer to the wiring diagram for connector pin identification.
