• An interconnected network of wires that transfer energy from the fusebox to other components
• Insulated cables are vibration and rot-resistant
• Signs of wear include faulty electrical accessories, erratic engine rev-ups, or slowdowns

Your INFINITI QX4 engine has an Engine Wiring Harness that runs along the entirety of your vehicle's electrical systems, from the engine to the fuse box to respective components. Similar to the human body's circulatory system, a vehicle's Engine Wiring Harness is comprised of a series of durable, insulated wires which transfer energy from the heart of the electrical system to all the INFINITI parts that need it.

Though your Engine Wiring Harness is made to last your vehicle's lifespan, it may need to be replaced if it becomes physically damaged. An Engine Wiring Harness can fray or malfunction if your vehicle is caught in a flood, exposed to extreme temperatures for prolonged periods, or if the component is improperly installed. If your INFINITI has started showing signs of a bad Engine Wiring Harness, visit an INFINITI service center near you for an inspection ASAP.

When ignored, INFINITI Engine Wiring Harness problems can cause unnecessary wear and tear on other engine components or even increase the risk of short circuits. Don't take any chances! Instead, take your vehicle to your nearest INFINITI experts for fast diagnostics. If a replacement is in order, be sure to install an exact replacement for optimal fitment and performance.
