The air suspension system electrical harness routing illustration shows the approximate routing of the harnesses and location of the interconnects used by the air suspension system. To locate and diagnose concerns inspect the wiring and connectors. A brief description of each harness follows:












- 14A435: Connects directly to the air suspension control module and air suspension switch. Connects to the 12614 harness in the front center of the luggage compartment. Connects to the 14401 and 14290 harness in the RH front cowl panel area.

- 12614: Rear under vehicle harness that directly connects to the air spring solenoid valves and the air suspension height sensor.

- G14401: Directly connects to the ignition switch, instrument cluster ("Check Air Suspension" Indicator) and fuse junction panel.

- 14290: Engine compartment harness that connects directly to the power distribution box and harness, air compressor, and air compressor relay. This harness also provides the compressor ground.

- The EVO line connects to the steering pump under the engine.

- 14A005: directly connects to all lamp switches and feeds the door open/closed information to the control module through the 14401 and 14A435 harnesses.
