Founded in 2023, All Wiring Diagrams is the leading online resource for automotive electrical system and wiring diagram information. Our mission is to make vehicle wiring easy to understand for DIYers and mechanics.
Our Story
All Wiring Diagrams was started by Michael Brown, an electrical engineer with over 20 years of experience working in the automotive industry. After helping countless enthusiasts troubleshoot electrical issues on forums, he realized there was a need for a dedicated site focused specifically on wiring diagrams.
Together with a small team of experts, Michael launched the site in 2023 to teach people how to read wiring diagrams and trace electrical faults like a pro.
