Custom Integration for High-Performance V8s and Rotaries
The Nexus S3 VCU + Plug and Pin Set is the hardware foundation for custom-wired 6/8-cylinder and 3/4-rotor applications. This kit includes the Nexus S3 VCU and the matching connector set, allowing professional fabricators to build a bespoke mil-spec harness that leverages the S3’s extensive features.
Mid-Range Nexus Power
The Nexus S3 bridges the gap in the Nexus lineup, offering 8 cylinder sequential support and PDM functionality in a compact package. With 4 x 25A high-current outputs, it can power fuel pumps, fans, and nitrous solenoids directly. The included plug set ensures a secure connection for all engine and power circuits, giving the builder complete control over wire routing and specification.
