What the pinout is for
The pinout diagram shows each pin on the Nexus R3 VCU's connectors and what it's for: power and ground, sensor inputs, injector and ignition outputs, general-purpose I/O and communications. It's the reference that ties a wire in your harness to a function in NSP.
When you need it
- Building a harness from the R3 plug and pin set or a universal wire-in harness.
- Adding a sensor or output to an existing install and choosing a free pin.
- Fault finding, when you need to confirm a signal at the ECU plug.
What to check
- You're reading the connector from the correct side. Wire side and pin side views are mirror images.
- The pin you pick supports the function you're assigning in NSP.
- High-current feeds and grounds use the correct pins and wire gauge.
