What Is A Wiring Diagram?

At InterConnect Wiring, Connections Matter – and wiring is our specialty! What exactly is a wiring diagram you ask? Let’s take a dive into one of our top blogs from 2016 and revisit one of our most-asked questions.




As you can see in the image above, wiring diagrams have been an important component to the wiring process for many years. This wiring diagram is for an old-school automobile, but it serves the same purpose as the wiring diagrams of today. As much as things change, they stay the same!


A wiring diagram is a simplified conventional pictorial representation of the physical connections and physical layout of an electrical system or circuit. In our world wiring diagrams show how aircraft wires are connected and where they should be in the electrical system, as well as the physical connections between all the components. This makes a wiring diagram useful in manufacturing or troubleshooting an electrical system or circuit for various aircraft including the F-16, F-15, B-52, and UH-60, among others. 


The difference between a wiring diagram and schematic is that the schematic only shows the plan and function for an electrical circuit but is not concerned with the physical layout of the wires. A wiring diagram is also different from a Harness Assembly Drawing (HAD), which is used by the assembler during manufacturing a wiring harness.


At InterConnect Wiring, we frequently use wiring diagrams to generate a Routing List (a point-to-point termination database). Once the terminations are in a database format we can extract Reference Designator Lists, Work Instructions for assembly, Batch Files for laser wire and Ref Des ID marking, as well as many other valuable pieces of aircraft electrical harness and circuit breaker production data.


It’s all connected to what we do to make sure everything is the best it can be, because Connections Matter!






Our License

We are the sole licensee of Lockheed Martin for F-16 electrical products. Through this agreement, we have access to Lockheed Martin’s F-16 engineering data, tooling and configuration control information. We also have a Technical Services agreement with Sikorsky for all of their aircraft. This agreement allows us to obtain their engineering data needed to rewire helicopters that Sikorsky manufactures.
