The existing injector harness can fail on certain D8T Track-Type Tractors, and 740B Articulated Trucks. If the existing harness fails it can cause a loss of engine performance. The injector harness can contact the valve springs if the harness routed incorrectly. If this happens the valve spring can rub through the harness causing a short circuit or an open circuit.
