Viper THNIN4 | T-Harness 2007-2016 Nissan/Infinity Key Type (DS4+ Only)

For traditional key Nissan and Infinity vehicles - DS4+ systems only.

Product Overview

The Viper THNIN4 T-Harness is a specialized wiring solution designed exclusively for installing Viper DS4+ remote start systems in select Nissan and Infinity vehicles with traditional key ignition from 2007 to 2016. Unlike the THNIN3 which handles SmartKey vehicles, this harness is engineered specifically for conventional key-turned ignition systems, providing plug-and-play connectivity that drastically reduces installation time.

Built for Nissan Motor Company's traditional key electrical architecture during this model range, the THNIN4 integrates seamlessly with conventional ignition systems and factory immobilizer technology. This DS4+ exclusive compatibility makes it essential for installers working with older Nissan and Infinity platforms that require specialized integration without SmartKey or push-button start systems.
