A replacement chassis wire harness for your Jeep may be adaptable to different models and features an OEM-style bulkhead connector that can mount to the original location. Chassis wire harnesses are customizable to perform with nearly any application and additional features include an auxiliary circuit with a relay capable of powering accessories like fog lights and electric fuel pumps. Circuit identification and color-coded wires make installation a no brainer and 4WD carries these components from top manufacturers including Painless Wiring and Omix-ADA. Circuits for everything from brake lights to wipers to A/C & heat can be addressed with a capable chassis wire harness.

Jeeps are incredibly versatile vehicles. Whether you rely on your rig to get you to work on time or to tear up an off-road trail, you need all its systems to function optimally. Wherever you drive, electrical problems can leave you stranded somewhere you might not want to be. 4WD.com has the Jeep wire harness inventory you need to repair your machine.

The Spark Your Rig Needs
Your Jeep's wiring harness is a series of wires that run throughout the vehicle. The purpose of a Jeep YJ wiring harness is to deliver electrical and other information to places your rig needs it. Many of the Jeep's systems have their own wiring harnesses. For example, your rig has a Jeep transmission wiring harness and an engine wire harness assembly. Unfortunately, over time, wiring harnesses can wear out. To be certain your machine has the spark it needs to perform, replace worn or damaged harness assemblies.

The Quality Products You Trust
You can't sacrifice quality when you are replacing any component in your rig's electrical system. To keep your Jeep running properly, replace damaged wiring harnesses with factory-grade components. At 4WD.com, we have top-notch replacement wires from manufacturers you trust. Pick harnesses with right circuitry to get your jeep ready for the trail.
