Second Hand Nissan Note Engine Wiring Loom

Yes, every Nissan Note has an engine wiring loom — it is the main harness that connects the engine management sensors, injectors, and ancillaries to the ECU, and every petrol or diesel engine variant of the Note requires one. The Note was sold in the UK across two main generations: the first-generation E11 (2006–2013) and the second-generation E12 (2013–2019). Because the loom is wired specifically to a particular engine, the engine code is the single most important detail you need to source the correct replacement.

Both years fall within the first-generation E11 (2006–2013), so you are within the same generation, which is a good start. However, fitment depends primarily on matching the engine code exactly — the E11 was available with different petrol and diesel engines during its run, and looms are wired to a specific engine variant, not just the generation. Confirm the engine code from your V5 or a VIN check and supply it to the breaker so they can match it accurately.

These are different generations — the E11 ran to 2013 and the E12 began in 2013–2014 — and crossing that boundary means a different bodyshell, revised engine lineup, and a redesigned engine management system, so the looms are not interchangeable. Even where an engine code appears in both generations, the connector layouts, loom routing, and ancillary wiring can differ. Do not attempt a cross-generation swap without confirming compatibility against your exact registration with the breaker.

Trim level — whether Visia, Acenta, or Tekna — does not affect the engine wiring loom; it is the engine code and fuel type that determine which loom is correct. The Note's trim grades differ in interior equipment, comfort features, and infotainment, none of which change the engine harness. Stick to matching engine code, fuel type (petrol or diesel), and gearbox type (manual or automatic/CVT), and the trim badge on the donor car is irrelevant.

Yes, gearbox type can matter because the engine loom on some variants includes connectors or wiring runs that interact with the transmission — particularly on CVT-equipped models where communication between the engine ECU and transmission control is integrated into the harness. Always tell the breaker your gearbox type alongside the engine code to avoid sourcing a loom with mismatched connectors. This is especially worth clarifying on E12-generation Notes, which were offered with a CVT alongside manual options.

Physically, a correctly matched loom — same engine code, fuel type, and gearbox type — should connect to the same sensors and plugs. However, whether the associated ECU or immobiliser system requires coding or reprogramming after a loom change is something you must confirm with the breaker or a Nissan specialist against your specific registration, as this can vary and is not something that can be guaranteed from the loom alone. Never assume a used loom is a straight swap without checking the ECU pairing situation first.
