I ordered this monitor to hook up to my BOSS DVD Player in my van so that kids had a screen to see a movie or to see what music track was playing. Hookup is very easy, even though the instructions are basic to say the least. Red wire to +12v, Black wire to -12v, Blue Wire is hooked up to a backup camera sense signal so that when the camera comes on, the monitor will automatically switch to the camera input. I did not use this cable as I do not have a backup camera, I just left it as is. There is no power on this cable so you do not have to worry about it shorting out to anything. The composite video cable gets plugged in from the source. I wired my monitor right to the power harness for the radio so that it turns on and off with the van and ran the cable under the dash out of the back of the radio area, looks clean and allows the monitor to be moved if needed.
The monitor is by no means a high resolution monitor, but it gets the job done and kids really do not care about the resolution so long as they can see the movie and subtitles if enabled, both of which are very usable on this monitor. If you need a cheap monitor for the kids, this will do just fine and it is cheap enough to replace should something happen to it.
