Yeah, off-topic too, but that's where I started as well. When I was young I was working as an electronics tech installing audio/alarm/video systems in cars and loved the work, but I wanted to go further so I went to school and got my electrical engineering degree. After that I was working in the medical field designing and building electronic medical devices, and just kept going until I finished my PhD. But cars have always been my passion, so I work on mine doing most of my own repairs and modifying them. In the last few years I've really gotten into the details of the communications bus systems because I needed to understand that in order to make the mods that I wanted. I've found that most of that has to be worked out through reverse engineering and trial and error because the manufactures guard it like Fort Knox.
