Aerpro SWSU14C Steering Wheel Control Interface Subaru Various Models Camera Retention
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.
Product Overview
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.
