TROUBLE DIAGNOSES — Wiring Diagram — Air Conditioner (engine-room half)
HA-42wiring diagramPin numbers are sparse on this engine-room half; many joints are bus-style connectors with multiple wires entering and exiting. Wire endpoint pins encoded as null where the diagram only shows the wire entering a connector body.

NOTE
Wire colour codes use Nissan single/double letter abbreviations (B=Black, W=White, R=Red, Y=Yellow, L=Blue, G=Green, BR=Brown, LG=Light Green; double codes are 'base/stripe' such as Y/B = Yellow with Black stripe).
