NOTE
Legend: All connectors shown in this illustration are unit-side connectors. Unit-side connectors with a double circle (⊙) are connected to the harness-side connectors shown in "Harness Layout for A/C System" (HA-67). The circuit numbers inside a connector coincide with the circuit numbers surrounded by a single circle (○). Switches inside the push control unit are mechanically linked to corresponding switches. (E) = For Europe; (G) = Except for Europe.
