Aerpro ASSU17C Steering Wheel Control Interface Harness for Subaru and Toyota
A CAN Bus steering wheel control interface harness from Aerpro, the ASSU17C suits select Subaru and Toyota vehicles and retains factory steering wheel controls, factory reverse camera (if originally fitted), factory AUX input (if originally fitted), and factory antenna, with reverse trigger, park brake, speed pulse, illumination, and amplifier remote 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).
Product Overview
The Aerpro ASSU17C is a vehicle-specific CAN Bus steering wheel control interface designed for select Subaru and Toyota vehicles, enabling 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. The kit includes an antenna adaptor, reverse camera retention adaptor, and AUX retention leads.
The ASSU17C 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), and factory antenna via the included adaptor. Outputs include reverse trigger (purple), park brake (green), speed pulse (pink), illumination, and amplifier remote. The ASSU17C uses a Type H patch lead and 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.
