Do you have a legend for sensor, wiring Illustrations

Question

Ok I’m old school so new to the advanced code readers scanners. I’m troubleshooting a likely bad open connection to a backup camera and trying to understand your illustrations . The circular symbols and circles with a slash across, red shaded areas ect. What exactly do they mean concerning a couple plugs I can’t get at well enough to see behind. Thanks for any advice on decrypting what those things mean.

Answer 1

Unfortunately, I'm not sure what illustration are you using. If you could post an image for me, I can try helping you with the diagnosis.
