a first controller, a second controller, a power source, a single wiring harness bundle, and a motor controller, wherein the power source is coupled via the single wiring harness bundle to the motor controller that is operatively connected to the electric machine;

wherein the motor controller includes a first circuit electrically coupled to a driver enabler of the motor controller and a second circuit electrically coupled to a driver of the motor controller;

wherein the driver enabler and the driver act in concert to operate the motor controller to control the electric machine;

wherein the single wiring harness bundle encloses a first signal cable electrically coupling the first controller to the first circuit, a second signal cable electrically coupling the second controller to the second circuit, a first power cable electrically coupled to the first circuit, and a second power cable electrically coupled to the second circuit;

wherein activation of the first circuit requires a first signal being transmitted from the first controller to the first circuit via the first signal cable;

wherein activation of the second circuit requires a second signal being transmitted from the second controller to the second circuit via the second signal cable; and

wherein activation of the motor controller requires activation of the driver in concert with activation of the driver enabler.
