The Bridge to Nexus Power for S13 SR20

For builders who already own a Haltech Nexus S2 or S3 ECU, or those upgrading from a universal wire-in setup, the Nexus S2/S3 Plug ‘n’ Play Adapter Harness is the essential link to the Nissan Silvia S13 SR20DET platform. This product is the adaptor harness only, designed to connect the sophisticated Nexus VCU directly to the factory wiring loom of an S13 SR20DET.

Manufactured with precision-molded connectors, this harness ensures a watertight and vibration-resistant connection between the Nexus unit and the Nissan harness. It is pinned specifically for the S13 SR20DET electrical architecture, managing power supply, sensor grounds, and actuator outputs.
