At Diesel Laptops we know that you want to be a better Diesel Technician. In order to do that, you need to know how to read electrical wiring diagrams. The problem is that every OEM draws their schematics differently, which makes you feel like you are starting over with every OEM. We believe that wiring diagrams should be consistently easy-to-read across OEMs, which is why we developed Diesel Wiring.
