Abstract: An integrated H-bridge electrical harness for controlling an actuator, such as a stepper motor, where the harness includes a signal converter in electrical communication with an ECU, a driver in electrical communication with the signal converter, and a plurality of connectors. At least one of the connectors provides a connection with the ECU, and another of the connectors provides a connection with an actuator. The signal converter receives a first type of signal (such as a pulse width modulated signal) from the ECU, and converts the first type of signal to a second type of signal, and the signal converter sends the second type of signal to the driver. The driver sends a third type of signal (such as a double square wave signal) to the actuator to control the actuator.
