Finding wiring diagrams for Mack Trucks can take time and effort. Mack doesn’t freely distribute wiring diagrams for their trucks, which often means you search the internet to find the wiring diagram you need. The more significant problem is that engineers often create wiring diagrams that aren’t built for technicians to diagnose their issues quickly. For example, the image below shows what a wiring diagram for Mack Truck looks like.

As you can see, following the individual wires and understanding all the symbols from the OEM Mack wiring diagram can be challenging.

The Wiring Diagram module from Diesel Repair is your solution to this problem. We put consistent, easy-to-read wiring diagrams into one location, allowing easy lookup and access. For example, this is the content you’ll find on Diesel Repair.

The symbols are more clearly defined, wires are color-coded properly, and each system is broken down into an easier-to-read format.
