Signs this part may need replacing: The harness may need attention if you see cracked, chafed or heat-damaged wiring, or loose or corroded connectors. Other possible signs are engine misfire, rough running, hard starting, or injector-circuit trouble codes. These symptoms can also come from other components, so diagnose the cause before replacing. If a damaged harness is the fault, the IFH2 is designed to replace it on the listed trucks and SUVs.
