How Many Wiring Harnesses Are In An Aircraft?

How many wiring harnesses are in an aircraft? The answer to this question is like answering how many seeds are in a pumpkin? There are thousands of aircraft models made by hundreds of manufacturers in existence and each of them is a complex piece of electrical and mechanical engineering.  There are a multitude of aircraft types such as bombers, helicopters, and jets. Because there is such a wide diversity in aircraft there is also a wide diversity in the number of harnesses in these aircraft.


Most aircraft range between 100-400 wiring harnesses.  This can vary based on aircraft type, model, and general design.  If an aircraft is retrofitted with all the “Bells and Whistles” so to speak, it can easily have upwards of 400 harnesses.    

InterConnect has worked on a wide variety of aircraft since its founding in 1993. We have manufactured entire ship sets of harnesses for the Sikorsky H-92, which has 261 wiring harnesses. For the USAF F-15C/D EPDS Program, we assembled all of the 170 wiring harnesses and 20 electrical circuit breaker panels and matrix assemblies for each of the 73 aircraft.  For the US Army National Guard UH-60 Black Hawk Rewire Program InterConnect manufactured 24 complete ship sets of 305 wiring harnesses and panels each, prior to installing them into the aircraft here in Fort Worth. Most recently InterConnect Wiring has designed and manufactured 101 wiring harnesses for each Iomax Archangel

By the way, on the average, a medium size pumpkin has 500 seeds.
