A CAN Bus steering wheel control interface harness from Aerpro, the ASTO14C suits select Toyota vehicles and retains factory steering wheel controls, factory reverse camera (if originally fitted), factory AUX input (if originally fitted), factory USB input (if originally fitted), and factory antenna, with reverse trigger, park brake, speed pulse, and illumination outputs, vehicle-specific plug for no-cut installation, and Type H patch lead. Recommended for installation with the Aerpro APP8 Secondary ISO Harness (sold separately).
The Aerpro ASTO14C is a vehicle-specific CAN Bus steering wheel control interface designed for select Toyota vehicles, enabling the installation of an aftermarket head unit while retaining factory steering wheel control functionality without cutting the original vehicle wiring harness. The vehicle-specific plug connects directly into the existing factory wiring for a clean, reversible installation.
In addition to steering wheel control retention, the ASTO14C retains the factory reverse camera output (RCA reverse camera input required on the aftermarket head unit), factory AUX input (RCA AUX input required on the aftermarket head unit), factory USB input (rear USB input required on the aftermarket head unit), and factory antenna via the included antenna adaptor. Outputs include reverse trigger (purple), park brake (green), speed pulse (pink), and illumination. The ASTO14C uses a Type H patch lead and is a CAN Bus interface type. Installation is further simplified when paired with the Aerpro APP8 Head Unit Secondary ISO Harness, sold separately.
Note: steering wheel control interfaces vary between vehicle models. Use the Aerpro Vehicle Selector to confirm the correct part for your specific vehicle before purchase. Aftermarket head unit must be SWC compatible. Steering wheel control functions may vary from OEM functions.

Retains Factory AUX Input - RCA Input Required: Factory AUX input is retained where originally fitted. The aftermarket head unit must have an RCA AUX input.
