Hi! I just installed a sony ax6000 into my 2017 Honda Civic Hatchback Sport. I bought it through crutchfield and bought the ready made harness. Everything worked perfectly right from the get go except that my backup camera wouldn't automatically boot on when I put it in reverse. I can still see the rearcam if I select it through the head unit but it doesn't automatically pop up when in gear. I then contacted crutchfield and they said since it was a manual I would have to t-tap the purple and white cord into a light green cord in a green 20 pin harness. I did this but it still isn't working. Any ideas? I used dorman t-tap for 16-14 gauge wire but I used 18 gauge wire.
