I am looking to add a light bar and train horn and have used rocker type switched in the past , but I cant seem to find the "right place" to put the switches. I have an EXT with the dvd player , so with no sunroof the molded headliner over the rearview mirror seems like a good place. thinking to get a piece of black abs plastic and trim it to the shape in the headliner and go from there ? any pic of other areas are appreciated
