Installation

This engine wiring harness is a direct OEM replacement that matches the original factory harness routing and connector locations. While the part is a bolt-on/plug-in replacement by design, engine wiring harness replacement is a labor-intensive job that requires disconnecting the battery, carefully labeling and removing all connector plugs, and re-routing the new harness through the engine bay. Professional installation by a qualified technician is strongly recommended to avoid damage to connectors or sensors. Always disconnect the negative battery terminal before beginning any wiring work.
