To my knowledge, this is the only wire harness interface that is available for hooking up a rear view camera (and front view also if you like) to the factory Mylink radio/video display on the 2016 (and other years also) Chevy Spark EV. I'm surprised this is not an available option to begin with. My goal was to install rear view cam without drilling one hole or cutting one wire in the factory setup. Goal accomplished with the aid of this unit. I now have working rear view cam in my Spark EV, no holes drilled, no wires cut.
