13 Ways to Design a Wiring Harness Poorly for Manufacturability
Posted by Jeanie Peel on August 20, 2018
So, you want to design a wiring harness. Here at InterConnect Wiring, we have had the pleasure of not only designing aircraft wiring harnesses for our customers, but also seeing thousands of other companies’ Build-To-Print (BTP) wiring harness drawing packages. As expected, we have seen some really good drawings & designs and frankly, some really … Continue reading “13 Ways to Design a Wiring Harness Poorly for Manufacturability”

What is an Aircraft Modification Kit?
Posted by Colton Peel on September 19, 2016
A modification kit is a set of wires and parts used to make upgrades to an aircraft. There are two main reasons for aircraft upgrades. The modification kits, sometimes called Loose Wire Assemblies (LWAs) are used to either standardize the aircraft or to improve service life. Standardizing the aircraft helps facilitate quick repairs in the … Continue reading “What is an Aircraft Modification Kit?”

Why Do Aircraft Have Wiring Harnesses?
Posted by John Ashour on September 5, 2016
A few months ago when I was interviewing a candidate for a new position at InterConnect I asked the prospect if he had any questions for me. He had a few about the company but he also asked two about aircraft. His first question was “How many wiring harnesses are there in an aircraft?” I … Continue reading “Why Do Aircraft Have Wiring Harnesses?”

What is Crosstalk in a Wiring Harness?
Posted by Nam Tran on June 20, 2016
Did you ever wonder why some wires are bundled together in one aircraft wiring harness and others are not? Why does this wiring harness have 6 breakouts while this other harness has only two? Why didn’t the Lockheed Martin, Boeing, or InterConnect engineer just add those two wires to the larger harness? There are several reasons, but one … Continue reading “What is Crosstalk in a Wiring Harness?”

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 … Continue reading “What is a HAD?”

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 … Continue reading “What is a routing list?”

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 … Continue reading “What is a BOM?”

What is a Wiring Diagram?
Posted by Nam Tran on March 21, 2016
A wiring diagram is a simplified conventional pictorial representation of the physical connections and physical layout of an electrical system or circuit. Wiring diagrams show how the aircraft wires are connected and where they should be located in the electrical system, as well as the physical connections between all the components. This makes a wiring … Continue reading “What is a Wiring Diagram?”
