Aerpro ASSU16C Steering Wheel Control Interface Harness for Subaru Factory Amplified Models with JBL and Harman Kardon Retention
A CAN Bus steering wheel control interface harness from Aerpro, the ASSU16C suits select Subaru factory amplified vehicles and retains factory steering wheel controls, factory JBL or Harman Kardon amplifier (if equipped), 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 ASSU16C is a vehicle-specific CAN Bus steering wheel control interface designed for Subaru factory amplified models, enabling installation of an aftermarket head unit while retaining factory steering wheel controls and the factory JBL or Harman Kardon premium amplifier system without cutting the original vehicle wiring harness. The kit includes an antenna adaptor, reverse camera retention adaptor, and AUX retention leads.
The ASSU16C retains the factory JBL or Harman Kardon amplifier (if equipped), factory reverse camera (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 ASSU16C 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. Some compatible vehicles are head unit dependent for full feature retention.
