A:AnswerI used an Axxess ASWC-1 steering wheel control adapter (about $45) for my 2012 Subaru Impreza and it only required connecting 4 wires (ground, accessory power, and 2 Impreza steering control wires in the car's stereo wiring harness) and plugging in a 3.5mm plug in the back of the Pioneer stereo. It programmed automatically once the radio was powered up. Simple. I expect the Chevy would at least as easy.
