Aerpro ASSU15C Steering Wheel Control Interface Harness for Subaru with Harman Kardon Amplifier Retention

A CAN Bus steering wheel control interface harness from Aerpro, the ASSU15C suits select Subaru vehicles and retains factory steering wheel controls, factory Harman Kardon amplifier (if equipped), factory reverse camera (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 ASSU15C is a vehicle-specific CAN Bus steering wheel control interface designed for select Subaru 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 and reverse camera retention adaptor.

The ASSU15C retains the factory Harman Kardon amplifier (if equipped), preserving the factory premium speaker system performance with the new aftermarket head unit. Factory reverse camera output is retained where originally fitted (RCA reverse camera input required on the aftermarket head unit). Factory antenna is retained via the included antenna adaptor. Outputs include reverse trigger (purple), park brake (green), speed pulse (pink), illumination, and amplifier remote. The ASSU15C 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.
