Quick update guys and gals! I got it working! It is actually plug and play with the existing harness. You just need to run a cable from the mirror to the camera.
Parts needed for the conversion:
-Rearview mirror I found mine on eBay from this seller:
-Cable to run from mirror to camera (PM me for info on the cable)
-Dual cameras (OEM)
You will need to cut out the hole above the license plate for the dual camera to fit in (It is about 1.5" wider) Easy to do with a dremel.
The new (dual cam) back up camera from the 17-19' is plug and play but it is angled differently from the 15-16' single camera. I will be working to adjust this or use my old camera in the new housing.
Overall it was pretty easy to do and cost me under $500. I am very happy with the results and happy I am now able to see behind me with the monitor screens dropped down!
I would like to figure out a way to hook up the video feed from the camera to my dash cam so I can record both front and back.
This awesome! I want to do this! Any more photos or video you can post on process?
