The Nexus R5 pinout diagram shows every pin on the Nexus R5 VCU connectors and what each one can do: its power and ground pins, engine outputs, sensor inputs, communications and general purpose outputs. It's the reference you need when you're:
- Wiring a universal harness, such as the R5 universal wire-in kit, into a car.
- Building your own loom from a R5 plug and pin set.
- Adding a sensor or output later and needing a pin that suits it.
- Tracing a fault with a multimeter.
What to check
- Make sure each pin's type matches the job. Input and output types are not interchangeable, so a sensor needs a suitable input and a load needs an output rated for it.
- Confirm you're reading the correct connector and looking from the correct side (wire side or pin side) before you push a terminal in.
- Cross-check your plan against the pin assignments in NSP, so the software and the harness agree.
