Next-Gen Control for the S13 SR20
The Nexus S2 Plug ‘n’ Play Adapter Harness Kit brings the future of engine management to the classic Nissan S13 SR20DET. This comprehensive package includes the Nexus S2 VCU and a dedicated adaptor harness, providing a leap forward in technology over traditional standalone ECUs. By combining engine control with a Power Distribution Module (PDM), the Nexus S2 allows for simplified wiring, advanced diagnostics, and robust power management.
Simplifying the Complex
The S13’s aging wiring can be a liability. The Nexus S2 mitigates this by taking direct control of power circuits and engine management functions. The included adaptor harness plugs directly into the factory ECU location, meaning no cutting or splicing is required. This setup supports all the specific needs of the SR20DET, including the optical CAS and factory idle control, while opening the door to modern features like flex-fuel tuning and drive-by-wire throttle control (with compatible hardware).
