Kenwood dnx6140 bypass

[Lucky 76 5]

My question has to do with the bypass. If I were to bypass by grounding the parking brake sensor will my rear view camera work? If so which wire am I supposed to splice on to under the dash? I do not need the color wire although that would be helpful but which wire am I supposed to be looking for?

Would I use the rear parking sensor or backup light wire?
