The AEM Infinity PNP Plug and Play Jumper Patch Harness (30-3520) is a universal ECU patch and extension harness engineered to work with a variety of engine management systems. This allows for the seamless integration of ancillary electronics such as turbo timers and data loggers, eliminating the need to cut or splice into your vehicle's factory wiring. The harness is designed for VQ35DE Manual Transmission applications, providing a direct plug-and-play connection. This harness is specifically compatible with the 2003-2006 Nissan 350Z and Infiniti G35 models equipped with the VQ35DE engine and a manual transmission. It supports various trims including Coupe, Sedan, and Convertible Roadster, and is also compatible with the RevUp engine variant (M/T Only) found in some 2005-2006 models. The plug-and-play design ensures a straightforward installation process. It is important to note that this product has been discontinued by the manufacturer and is no longer available for purchase.
