What is a HAD?
Posted by Chris Bettinger on June 13, 2016
A HAD is a Harness Assembly Drawing used to aid in the manufacturing of electrical wiring harnesses. HADs are used in the aerospace industry for all aircraft platforms including the AH-1F, AH-1Z, B-1B, B-52, C-130, EC-130, F-15, F-16, F-22, etc. Before production of a harness, a HAD is printed in full scale (1:1) to ensure the • Read More >>

What does it Mean to “Beep Out” a Wiring Harness?
Posted by Clare McGarrey on June 6, 2016
Wiring harnesses are crucial to aircraft as well as anything that requires electrical power. Often InterConnect has customers approach us because they have a project that is behind schedule, there’s an inoperable aircraft on ground, or a crucial modification needing to take place in the field before the aircraft can be mission ready. Our customers • Read More >>
What is a routing list?
Posted by John Ashour on May 30, 2016
A routing list (commonly called an ‘RL’) for an aircraft is a list of each wire in a wiring harness. Routing Lists are used on all aircraft including F-16, F-22, F-35, V-22, UH-60, CH-53K, etc. It is called ‘routing’ because it contains the endpoints of each wire. For example, wire NAV-121-22 may go from reference • Read More >>

Why Does Each Wire on an Airplane Have Its Own Identification Number?
Posted by Marc Piloian on May 24, 2016
In brief – to ensure the airworthiness of the aircraft. Any modern aircraft, especially fighters like the F-15, F-16, F-22 and F-35 have thousands of wires. The integrity of the electrical wiring interconnect system (EWIS) affects the ability to gather data, communicate, fire weapons and even control the aircraft in flight. Now imagine you’re a • Read More >>

Why do some wires have a metal shield around them?
Posted by Candace Evans on May 10, 2016
In the 1970s when you were in your house watching TV, and someone plugged in a vacuum cleaner or turned on a blender, it completely affected the picture on the television. It magically produced terrible, crooked lines on the screen. For the younger reader who has never witnessed this before, take a look at the • Read More >>

What is a Synthetic Harness?
Posted by Clare McGarrey on May 2, 2016
In the aerospace industry, or at least here at InterConnect Wiring, we use the term Synthetic Harness. Now I cannot remember if InterConnect came up with the term or if it was our customer, Lockheed Martin, but I do remember when it did come to fruition. It was back in 1999 and InterConnect was asked • Read More >>

What is insulation resistance testing?
Posted by Mike Winters on April 25, 2016
Every electrical wire, whether it’s in an F-16 cockpit panel, UH-60 circuit breaker, or V-22 wiring harness, is carefully protected with some type of electrical insulation. The wire itself is a conductor of electricity. The insulation is opposite from the conductor; it should resist current and keep the current on its path along the conductor. • Read More >>

What is a BOM?
Posted by Randall Robinson on April 19, 2016
I once asked my wife if she knew what the BOM was for something. The look I received was pure confusion and bewilderment. For example, “what is the BOM for parmesan chicken” is not the usual question a wife expects from her husband. Though poorly worded the question is valid. What is a BOM and • Read More >>

What is a standard part versus a non-standard part?
Posted by Chris Vardy on April 11, 2016
In the 1980’s, the fast food chain Wendy’s had a commercial advertising chicken sandwiches with a tag line stating “parts are parts”. InterConnect Wiring has been assembling wiring harnesses and electrical panels with both standard parts and non-standard parts for the past 23 years. But parts are parts, right? When the Department of Defense started • Read More >>
