Steering Wheel Button Control Adapter for Ford ACV SWC 42XFO020-0

Preserve the original radio control functions from the steering wheel when replacing the factory radio with an aftermarket unit. Depending on the vehicle equipment, range of functions and the software of the newly installed head unit, some functions may be limited or replaced by others. Compare the displayed wiring connectors with the connectors in your vehicle and ensure they match both technically and visually. Check whether one of the listed OEM head units was originally installed. Before final installation, verify vehicle functionality, system settings and correct operation of the steering wheel controls.
