Furrion rear camera

  Thank you but I think I will just hook it up to the reverse lights and forget about driving forward with camera on.

   I am trying to decide how to wire a rear camera mounted to the top back of our fiberglass cap on the back of our truck. Our truck does not have a optional rear camera so I thought I could buy a rear camera to use with the Furrion monitor that we use for the camera mounted to the back of our camper. But not sure how I should wire it I am thinking best would be somehow to a wire that's connected to the ignition switch but I don't know what wire that would be that's located in the back of the truck. Or else I could wire to the reverse lights and just use it for backing up. But I thought It might be useful to have the rear camera when driving down the road. Does the wire that's part of the seven pin trailer connector the one that charges trailer battery does that only work when ignition switch is turned on? Thank you for any help you can offer! I am not much of a electrician!
