NATS (Nissan Anti-Theft System) / Gasoline engine — Wiring Diagram
EL-7058wiring diagramThree separate fuse-protected branches (one ignition, two battery) — necessary because IMMU must read the key transponder before ignition allows the engine to crank, and must keep memory alive over a key-OFF.

NOTE
Cell-level NATS harness wiring. NATS IMMU (M146) is at the ignition-key cylinder. Power feeds reach it from three fuses: 10A [25] (ignition ON/START) and 10A [20] + 10A [24] (battery branch — IMMU constant and security-indicator feed). The IMMU communicates with the ECM via P/B (engine-control harness), with the audio unit via W/B (AU variant) and with the Super Lock control unit via LG (SL variant). NATS security indicator (M27) is driven by G/B + Y/B from the IMMU.
