Steering Wheel Interface Control

Q: What do the wire colors of a car stereo mean?

Car stereo wiring is color coded for convenience and simplicity. Each wire color has a specific meaning, we show you what they are.

Steering wheel interface control allows you to control your aftermarket car stereo receiver with your factory steering wheel controls. We offer a direct hardwired wire connection between your steering wheel and your aftermarket car stereo to ensure reliable operation..

Steering wheel interface controls enable driving to be safer. Drivers have the convenience of selecting radio stations while their eyes remain on the road, and hands stay firm at 9 and 3.
