Can someone help me with how to route the harness to the screen? Is it behind the metal part on the left or the plastic in the right? I tried begin plastic on the right but then the cables come out the front over the radio. When I try behind the metal part there doesn't seem to be space as the cavity is a plastic bucket like piece for the radio that goes all the way to the top. It's unclear in the videos can someone help?
Like the guy does it in this video at 15:10 where he goes just behind the first black plastic is this correct?
