Underneath the steering wheel column, there is a "hush panel" plastic panel that is just clipped in (just above your knees). You can pull that down. Up in there somewhere is a silver box tucked away that is the video control box. There is a blue wire that comes off of that.
The camera before the one we're using now had issues with not being able to adjust the volume down so I think they stopped hooking that up. If that blue wire is there, you can connect that to the "REVERSE" lights 12v power line on the Ford chassis. That will ensure that the volume only comes on in reverse.
