Both there is 2 wires for the video
If you stip back your video lead the outside sheild goes to pin 6 and the center core of cable (usually yellow for video) goes to pin 4. Make sure you strip it so its not shorted.
Although from what I have seen the factory leads they use pin 5 as the shield. So 5 or 6 will do.
Once you get the video to work it will most probably be blocked whilst driving.
The english conversion can unblock this. Or you can get a TV override box and loom.
Try watching your factory TV and see if a message comes up and the screen goes black when you dive. Then you will need it over ridden
