This harness utilizes OEM-quality connectors and is engineered specifically for the SC400's factory wiring layout. The \"plug-and-play\" design means no permanent modifications are necessary; there's no cutting or splicing of the factory wiring, making the entire installation fully reversible. This ensures that your vehicle can be returned to its original stock configuration at any time.\n\nFor models equipped with automatic transmissions, the factory ECU will continue to manage transmission functions while the Haltech Nexus takes full command of the engine. This approach allows for optimized engine performance and tuning without compromising the transmission's operation.\n\nBy upgrading to the Haltech Nexus system, you can expect significant improvements in throttle response, making it more precise and proportional. The kit enables fuel and ignition timing to be meticulously calibrated to your specific engine modifications, moving beyond Toyota's conservative factory settings. Furthermore, it ensures stable idle control regardless of ambient temperature and consistent engine behavior across the entire operating temperature range, providing a robust tuning foundation tailored for this specific chassis. This kit is intended for competition and off-road use.","brand":"Haltech","offers":[{"title":"Default Title","offer_id":52872130658616,"sku":"HT-651376","price":3597.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/nexus-r3-vcu-plug-n-play-adapter-harness-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
