Reverse Wire, Backup Camera, 2015 Hyundai Santa Fe

I think you need to tap into it, brown from the stereo to the red / black should getting the screen to change when the car is in reverse. Then the Blue/white from the axxess harness (camera power) to the red accessory wire.

So I did finally get it working. It was the black/red wire from the vehicle’s wiring. As I mentioned, I had purchased an Axxess harness to retain the factory camera. So I traced which harness wire corresponded to the black/red Hyundai wire, tapped into that, joined it with the radio’s reverse wire and the 12volt-to-6volt converter wire and…it worked! Thanks for your help!
