Just to save a little on some questions. When Mike starts the build along he is going to post web sites where you can get all of the following, detailed directions for a particular build, supplies(wiring harnesses,cases, boards), what cameras can be used and what can't, etc. It is really easy to order things once you get started. Most of the time all you have to do to get a kit is click on the camera you are going to use and the kit comes drilled and ready. And the guys on the sites are like Trad Gang, they love to help!!!
