Wiring harness for NCR60E, 4L60E, 4L65E, and 4L70E transmissions (1993–2008). Compatible with both 2WD and 4WD systems. Key benefits Ensures correct communication between the engine control module and the transmission shift mechanism so shifts occur reliably and predictably. Reduces installation time and effort with factorystandard fit and plugandplay connections—no splicing or wiring changes required. Built for durability and consistent electrical performance under temperature conditions to minimize failures and repeat repairs. What makes it stand out Direct compatibility with NCR60E, 4L60E, 4L65E, and 4L70E transmissions made from 1993 through 2008, covering common 2WD and 4WD vehicle setups. Copper core wiring for electrical conductivity and stable signal transmission between the ECM and the shift interface. Heatresistant materials and construction to protect internal wiring in underhood and transmissionadjacent environments. Manufactured to original factory standards with reinforced ring terminals for strong, reliable connections. Plugandplay design prevents the need for modifications during installation. Technical attributes Function: wiring harness that interfaces the engine control module (ECM) with the manual shift mechanism/standalone shift controller to enable precise clutch engagement and gear changes. Compatibility: NCR60E, 4L60E, 4L65E, 4L70E transmissions; model years 1993–2008; supports both 2WD and 4WD configurations. Materials: copper core conductor for conductivity; heatresistant insulation and protective materials for long service life. Installation: reinforced ring terminals and factorystandard connectors for straightforward, nomodification installation. Typical applications / use scenarios Transmission or rebuild: a worn or damaged internal harness during a transmission rebuild to restore reliable ECMtoshift communication. Transmission swap or donor installation: Use when installing a compatible transmission into a vehicle (1993–2008 2WD/4WD) to ensure proper electrical connections and shift control without custom wiring. Field or service replacement: Quick, plugandplay replacement for fleets or vehicles that experience harness damage from heat, wear, or mishandling, minimizing downtime. Installation notes Designed to meet original factory routing and connection standards; follow vehicle service manual for connector locations and torque specifications for ring terminals. No additional wiring modifications should be for compatible transmissions and model years listed.
