To fish the camera wire to the back of the rig, pop off the plastic cap in the center of the rear roof covering the body side of the latches, then take out the upper center console by removing the rear fascia piece, and accessing two t20 torx screws at the rear. This fascia is held on by the faux Allen screws and center snaps you cannot see and have to pry down. I suggest plastic trim tools. When these t20s are removed gently pry down at the rear and switch plate will swing down pivoting at the front.
To fish, put a slight end curve on a steel fish to work around any roof structures and you’ll pop out at the roof center console. I added an extra pull string to make any future pulls easier.
To get the unit side of the camera wire out to the windshield, I just stuck the pointy end of an 18” tie wrap up from the windshield side, taped the connector on, and gently pulled working it thru the gap.
Oh, and the disposable snaps holding the rear plastic are stronger than the cover itself, so if you’re like me, you’ll be repairing it with epoxy later.
The rest others have demonstrated. Pick your poison drone there.
