PAC interfaces bridge the communication gap between the factory-installed steering wheel controls and an aftermarket audio system. These devices are engineered to interpret and convert electrical signals sent from the steering wheel buttons into commands that the new audio system can understand.
Key Components of a PAC Interface:
- Steering Wheel Control Adapter (SWC Adapter): This is the core component that processes signals from the steering wheel buttons.
- Wiring Harness: A set of wires that connect the PAC interface to the vehicle’s existing wiring system and the aftermarket head unit.
- Programming Module: Some PAC systems require initial programming to match the specific make and model of the car. What Does PAC Stand for in Steering Wheel Control?
