Water and electricity do not mix. In automotive, marine, and outdoor industrial environments, moisture is the absolute worst enemy of an electrical system. If water breaches a wire harness connector, it causes rapid galvanic corrosion, leading to intermittent faults and eventual complete failure. Knowing how to select the right wire harness connectors for waterproof applications […]

When a wire harness operates in an engine bay, deep underwater, or in outer space, standard plastic connectors and wire insulation materials are simply not enough to keep out moisture and prevent vibration damage. To achieve ultimate reliability, manufacturers rely on two advanced chemical processes. Understanding the role of potting and conformal coating in wire […]

A wire is not a perfect conductor; it is essentially a very long, very weak resistor. When electricity travels over a long distance, some of that electrical pressure (voltage) is lost as heat due to the natural resistance of the copper. Knowing how to calculate voltage drop for long wire harness runs is essential to […]

When designing a wire harness for a vehicle, most engineers obsess over heat resistance. However, for snowmobiles, aerospace applications, and heavy machinery operating in the arctic, the impact of extreme cold on wire flexibility and durability is an equally deadly engineering challenge. Cold weather does not affect the copper conductor itself (in fact, copper becomes […]

Building a wire harness is only half the job; proving that it works perfectly before installation is the other half. Knowing how to properly test a wire harness for continuity and shorts is the firewall that prevents expensive electrical failures in the field. A single mispinned wire in a 200-wire harness can completely disable a […]

A custom wire harness is a complex 3D object, often winding its way through engines, bulkheads, and chassis. However, before a single wire is cut, it exists entirely as a 2D map. Knowing how to read and understand a basic wire harness schematic is the most important skill for any electrical engineer or assembly technician. […]

Before a wire can be crimped to a terminal or soldered to a connector, its protective insulation must be removed. This process seems incredibly simple, yet the critical importance of proper wire stripping techniques is often underestimated. In professional wire harness manufacturing, a bad strip is an automatic quality control failure. Stripping a wire is […]

When opening the walls of a residential house, you will almost exclusively find stiff, thick copper wire powering the electrical outlets. However, if you open the wiring harness of a car, airplane, or industrial robot, you will find incredibly flexible wire made of hundreds of tiny hairs. Understanding the difference between stranded and solid wires […]

When bundling and protecting a wire harness, tape is one of the most versatile and cost-effective tools in a manufacturer’s arsenal. However, not all tape is created equal. Knowing how to select the best wire harness tape for high temperature environments is critical for preventing catastrophic electrical failures in automotive engine bays and industrial machinery. […]

When designing a wire harness for a harsh industrial, automotive, or aerospace environment, simply bundling the wires together is not enough. They require an outer layer of armor. This is why braided sleeving is crucial for wire harness durability. Unlike rigid plastic conduits or sticky electrical tape, braided sleeving offers a unique combination of extreme […]
