An analogue steering wheel control interface engineered for various Subaru vehicles, the SWSU14C retains factory steering wheel controls and the OEM reverse camera, provides reverse trigger and park brake outputs, and retains the OEM AV socket, with a vehicle-specific plug connection requiring no cutting of the factory wiring harness.
The Aerpro SWSU14C is an analogue steering wheel control interface designed for various Subaru vehicles. It includes a harness fitted with a vehicle-specific plug that connects directly into the existing factory wiring in the vehicle without cutting or modifying the factory harness. The SWSU14C is compatible with SW-type patch leads (sold separately), supports the OEM phone button and Voice Assistant button when connected to a compatible aftermarket head unit, retains the OEM reverse camera when equipped, and retains the OEM AV socket. OEM reverse camera retention applies only if the vehicle was originally fitted with a factory reverse camera, and the aftermarket head unit must have an RCA camera input for the camera to display. The 5-pin camera plug should be disregarded if not present in the vehicle, as the camera signal is also wired through the main plug.
Outputs include reverse trigger (purple wire) and park brake (green wire). Custom button remapping is available and requires a USB-C cable (sold separately). Installation is simplified when the SWSU14C is paired with the optional Aerpro APP8 Headunit Secondary ISO Harness (sold separately), which connects between the aftermarket head unit and the SWSU14C interface. The aftermarket head unit must be SWC compatible and steering wheel control functions may vary from OEM functions. Use the Aerpro Vehicle Selector to confirm the correct part for your specific vehicle before purchase.
Retains Factory Steering Wheel Controls with Aftermarket Head Unit: The SWSU14C allows the factory steering wheel audio controls to operate with a compatible aftermarket head unit, maintaining hands-on-the-wheel control without requiring the driver to reach for the head unit directly.
OEM Reverse Camera Retention: The SWSU14C retains the factory reverse camera when connected to a compatible aftermarket head unit with an RCA camera input. Camera retention applies only if the vehicle was originally fitted with a factory reverse camera. The camera signal is wired through the main plug; the 5-pin camera plug should be disregarded if not present in the vehicle.
OEM AV Socket Retention: The SWSU14C retains the OEM AV socket functionality when connected to a compatible aftermarket head unit.
Vehicle-Specific Plug - No Wire Cutting Required: The SWSU14C harness is fitted with a vehicle-specific plug engineered to connect directly into the existing factory wiring in the vehicle. No cutting or modification of the factory wiring harness is required, simplifying installation and preserving the factory wiring integrity.
Analogue Interface Type: The SWSU14C uses an analogue interface type, compatible with the steering wheel control signal architecture used in the supported Subaru vehicles.
OEM Phone Button and Voice Assistant Support: The SWSU14C supports the OEM phone button and Voice Assistant button when connected to a compatible aftermarket head unit.
Reverse Trigger Output (Purple): A reverse trigger output via a purple wire enables automatic switching to the reverse camera input on the aftermarket head unit when reverse gear is selected.
Park Brake Output (Green): A park brake output is provided via a green wire, supplying the park brake signal required by compatible aftermarket head units for safety feature operation.
Custom Button Remapping Available: The SWSU14C supports optional custom button remapping to customise the steering wheel control button configuration. Remapping requires a USB-C cable (sold separately).
Compatible with Aerpro APP8 Secondary ISO Harness: The SWSU14C is recommended to be installed with the Aerpro APP8 Headunit Secondary ISO Harness (sold separately), which connects between the aftermarket head unit and the SWSU14C interface for a simplified and complete installation.
