Don't panic - I think I thought the same thing when I added the hardware to my 2016. IIRC you're not looking in the right spot. Post a picture.I have a 2017 CX-9, but it appears my CMU must not be compatible because I only see one brown port on the back. And it's not keyed correctly for the blue or green wires. What gives? I thought all the 2017 models and up were good to go?
