Backup Camera

[RJW60548]

Hello,
I have a 2009 Isuzu NPR=HD that I am trying
to install a backup camera onto. there are three wires coming from the monitor. Red= switched power supply, Black = Ground, (and the confusing one). Green= Reverse signal.
Does anyone have any idea where the GREEN wire hooks to under the dashboard? it is supposed to send a signal to the monitor to wake up when the truck is placed into reverse.

normally it would go into the wire tied into the reverse switch so the camera comes on when you put the vehicle in reverse. Which wire that would be in your vehicle I have no clue.

Thank you , Shadrach. I understand what the wire is supposed to hook to. I was hopping someone could tell me how to find that wire, what color it is, or where its located. I would even settle for a 2009 wiring diagram.
someone told me to get a fuse tap and install it in the backup light spot of the fuse block. not sure if that would work

You would probably have better luck doing a Google search for the wiring diagram for your truck or a Isuzu truck forum. I doubt anyone here has the knowledge you are seeking.

Thanks Bill,
It was only after hours of Googleing and coming up empty handed that I grasp at straws and come here
