I have a back up camera, monitor, and wireless transmitter I wanted to hook up but I'm really sure how to do about it. I know how to hook up the camera and transmitter to the tail light. The problem I'm having is figuring out what wires to use to hook up the receiver and monitor. I got it mainly for the back up cam but I wouldn't mind if I could use it for other things as well like DVDs and what not. Any help would be much appreciated and I thank you in advance. Here are some pictures of what I'm working with.

 

What kind of input's does the monitor have? The way it looks there is the receiver just has 1 yellow wire and the small power wires, the yellow is video. If the screen has more than one input than you should be able to plug other device's into it. Hopefully that helps, post pics of the inputs on the screen if you can.
