A SWC harness from Aerpro for compatible Mazda vehicles, the ASMZ4C retains factory steering wheel controls and factory antenna when installing an aftermarket head unit, with a vehicle-specific plug for direct connection without cutting factory wiring and patch lead type H compatibility. A compatible SWC patch lead is required separately for SWC function.
Product Overview
The Aerpro ASMZ4C is a SWC harness type H engineered for compatible Mazda vehicles, providing steering wheel control retention and factory antenna retention in a single harness assembly to simplify aftermarket head unit installation. The vehicle-specific plug connects directly into the existing factory wiring without cutting or modifying the original harness. The included antenna adaptor converts the factory Mazda antenna connection to a standard DIN plug suitable for aftermarket head units. A compatible type H SWC patch lead is required separately for steering wheel control function. Installation is simplified when paired with the Aerpro APP8 Secondary ISO Harness (sold separately).
