I am thinking about purchasing the ford emblem camera kit its been installed all these write up dont explain what wire you have to look for in the rear to hook up the camera harness. I want to hook the camera to the navigation unit is my goal, but trying to find out more information to see if I have the wire installed in my vehicle before I buy camera kit.

Do you know where this wire is usually located?
