How can I do this ELS mapping?

Ok so I want to add some lights on this model ('?do=embed' frameborder='0' data-embedContent>>) for my personal use. However... I do not know how to map els lights onto a car model. I know I have to use zmodeler, but I do not know where to get the lightbar models and how to position them on the vehicle and make them els compatible. I was hoping someone could explain to me how to do this by myself, and if you are willing enough to do it for me that would be greatly appreciated. I have attached pictures of a RCMP cvpi with circles drawn on it. The circles represent where i want to add lights, which are located on the lightbar and front window, and the color of the circle represents what color i want the light to be. I will also post a picture of a real life Charger in which i circled where i want more lights (by the license plate). Lastly, i will attach a photo of an unmarked charger and i did the same, i put circles where i want to add lights onto the charger (link above). If there is any easy way to do this please help, or if you have suggestions, questions, or any help please comment below. Thanks again, -Chaz.
