2012 Reversing Camera

[NearlyThere]

Hi all,

I have a blue screen that is intermittently appearing on my reversing camera. I have checked the connector on the camera and continuity checked the wiring to the connector on the rear hatch and it is fine.
I have wiggled the wiring in the conduit from the rear hatch to the body and it makes no difference.

Can anyone direct me to how I identify the next connector to check the continuity of the rest of the wiring? A wiring diagram with connector locations would be useful.

The fact that it is intermittent suggests wiring to me but any thoughts or history on this type of snag would be useful.
Thanks

Neil
