Nexus S3 Plug ‘n’ Play Adapter Harness Nissan Skyline R34 GT-T

Nexus Integration for the R34: S3 Adaptor Harness

The Nexus S3 Plug ‘n’ Play Adapter Harness is the essential link for installing Haltech’s Nexus S3 VCU into the Nissan Skyline R34 GT-T and Stagea WC34. This harness is engineered to leverage the S3’s advanced processing power on the RB25DET NEO platform without the need for a custom wire-in installation. It connects directly to the factory ECU header, mapping the vehicle’s sensors and actuators to the Nexus S3’s inputs and outputs.

Engineering for the Nexus S3

This adaptor allows the Nexus S3 to take full control of the NEO engine. It supports the variable cam timing (VCT) system and provides the necessary TPS load signal for the ATTESA AWD system on Stagea models. The harness includes an auxiliary I/O connector, allowing users to easily add aftermarket sensors like wideband O2, fuel pressure, and oil pressure directly to the VCU. This data can then be used for advanced engine protection strategies and data logging.

Operational Benefits

With the Nexus S3 and this harness, you can unlock features like launch control, traction control, and flex-fuel tuning. The harness maintains the function of the factory dashboard, including the tachometer and coolant temp gauge. It is the cleanest way to install a Nexus S3 into an R34 GT-T, providing a professional, reversible installation that retains the reliability of the factory wiring loom.
