NATS (Nissan Anti-Theft System) / Gasoline engine — Wiring Diagram — NATS (Supplement-VII)

Detailed NATS gasoline wiring. Supplement-VII changes vs Supplement-VI: • Super-lock CU added as a NATS-authorisation peer (IMMU pin 3 → SUPER LOCK CONTROL UNIT M105 via M108 inline, LG wire). • ECM authorisation routing changed — P/B from IMMU pin 1 now goes via M183/F57 inline pair to ECM F62 (Supplement-VI used M163/F33 / M23/F28 for LHD/RHD variant inlines). IMMU pin assignments (M146): • Pin 8 — Y/B (battery feed via M14 cell 11U) • Pin 7 — P (ignition feed via M14 cell 31U) • Pin 6 — LG (security indicator drive) • Pin 4 — B (ground) • Pin 3 — LG (super lock CU — new in Supplement-VII) • Pin 2 — G/B (audio unit NATS link) • Pin 1 — P (ECM authorisation, becomes P/B after engine-control-harness inline) Wire colours match Supplement-VI on the IMMU side; ECM-side P/B (Purple with Black) is unchanged.
