Freightliner Trucks is the largest truck manufacturer in North America, so it is no surprise that customers often look for wiring diagrams for their trucks. This includes the most popular models, such as the Freightliner Cascadia, Freightliner Columbia, and the Freightliner M2. Unfortunately, Freightliner doesn’t make it easy for their customers to get access to technical information such as wiring diagrams.
Ease of Use
Our platform not only includes Freightliner wiring diagrams but also diagrams for other truck manufacturers and models as well. Making the wiring diagrams have the same look and feel across both models and manufacturers is essential since it allows your technicians to be more efficient. For example, you’ll see the same symbols on this Freightliner Cascadia wiring diagram for front turn signal lamps used across other manufacturers.
Whenever possible, we make sure to color code the wiring diagrams to match the actual colors of the wire on the vehicle itself, which often exceeds what the OEM wiring diagrams look like. This is an example of a Freightliner Cascadia trailer receptacle wiring.
