Easily remove aftermarket electronics such as boost controllers without a visual trace that they were ever installed by using this high quality ECU patch harness. This item installs between the stock ECU/ECM and the stock engine wiring harness. This allows users to have a plug and play wiring harness extension so they can tap in aftermarket electronics such as a boost controller, datalogger, or other devices without having to splice into the stock wiring to obtain signals such as 12V power, ground, RPM/tach signal, mass air flow signal, air intake temperature sensor, throttle position sensor, factory wideband sensors, and others. The stock wiring harness is very expensive, so this can save you time and money in the long run and also helps the resale value of the GT-R. It is made in the USA.
