 Engine Wiring Harness

The electrical system in your vehicle provides power to your engine, much like your blood vessels supply oxygen to your body. When the electricity in the vehicle doesn't carry through properly, it can cause your Jeep to catch fire or to simply shut down. The Jeep engine wiring harness is the system that keeps the electricity moving correctly through the engine to give you the best experience whether you're on the road or taking your Jeep off-road for a day of fun.

Understanding the Electrical System
The engine wiring harness carries the current from the battery to the fuse box, where the power is redistributed to the electrical components of your engine, such as the instrument panel, radio and lights. If you are replacing the engine wiring harness, you should make sure to have a shop manual for your Jeep to make sure to get the wires back in the right place. Pay close attention to every aspect of the process and take precautions to ensure your safety.

Tips to Avoid Making Mistakes
Take pictures of your current wiring harnesses to capture the detail of how the wires are routed and connected before replacing your current Jeep engine wiring harness. You can label the wires with masking tape for a way to quickly identify each one during the reinstall. Disconnect the battery and remove it from the vehicle, if possible. Place it in a cool location, away from your workstation while you are making repairs.
