You need to figure out if your radio video display is NTSC format. It probably is. When I was trying to figure out what wire did what I plugged the backup camera into a TV and it worked. If it is NTSC, find out what inputs you need to provide the monitor. My original post has the pinouts for the camera. At a minimum, you will need to provide NTSC+ and NTSC-. Let us know what type of connector it is. When you wire it up, you will want to manually activate the camera at a minimum. Having it come on automatically when the truck is in reverse is also helpful.
