about Wire Harnesses​

A wire is a strand of material, conductive material,  that conducts electricity, such as aluminum or copper.

Cables are usually braided or twisted strands of conductor that’s then sheathed in protective material.

A wire harness is a collection of cables or wires with protective covers, sheath material like thermoplastic. In another word, a wire harness is a simple exterior sheath that covers some wires or cables.  Wire harnesses offer a low-cost solution, for they provide a bundle of cables and wires with some degree of protection while keeping them organized for ease of installation and future service.

When it comes to a brief explanation of cable assembly, it provides much more robust protection by keeping components snug within a rugged outer sheath. For this reason, cable assemblies can shield the interior wires and cables from heat, extreme heat, friction, moisture, abrasion, compression, and other hazards. 

 But people often take electrical wiring harness, loom, cable assembly, wiring assembly, coax cable, RF cable, injection-molded cable assembly, fiber optic cable, cable harness as one thing.

Heavy duty wiring harnesses are used for a wide range of applications to power large, heavy machinery. They come in various sizes and types depending on the current, voltage, frequency, or temperature that they will be exposed to.
Cable ties are small plastic strips that can be used to bundle or secure wires, cables, and other cords.
A car’s electrical system needs a power source to function properly. A wire harness provides the necessary connection between a different power source such as batteries and alternators in order for them to be able to work together without interference from one another.
Wire harnesses are a crucial part of electronics, and the size or thickness can have significant consequences. A wire with too low an electrical requirement is prone to overheating due to poor insulation while likewise one that has requirements that exceed its capacity may also overheat but for different reasons. Electrical conductivity is a measure of the ability to transmit an electrical current. A wire harness should have a low impedance in order to reduce power loss due to resistance and crosstalk, but not so much that it causes excessive attenuation or signal distortion.
 It has a simple push-button design that allows you to turn the light on and off with ease, even while wearing gloves or in low visibility situations like nighttime driving. The connector also works well as an emergency backup source of power when your vehicle battery dies!
A wire harness assembly process is responsible for linking the electrical components of a vehicle to one another. The final product should be able to withstand rigorous testing and will need an impeccable design in order to function properly. So, finish the installation by professionals or under the guidance of professionals. Making wire harnesses is no easy task, but at least we’ve got some simple wiring for you!
There is strain on wiring system from being pulled, bent, or simply flexed over time, so wire harnesses need a strain relief to keep the wires from becoming loose or breaking.
The wiring harness – wishbone style is the most efficient way to wire your car. In general, it’s less of a hassle and easier on both you and your vehicle when you use this type of wiring as opposed to standard two-wire arrangements in cars made before the 1990s or so.
Wire harnesses are called many different names, including electrical wiring harnesses, looms, cable assemblies, wiring assemblies, cable harnesses, coax cables, RF cables, injection-molded cable assemblies, fiber optic cables, and many times are simply called harnesses. They are used in a variety of applications from airplane engines to commercial and residential electrical wiring. 
The extendable wiring harness is designed to be used with any tripod, light stand, or boom pole. It can be easily attached and detached from your equipment for quick setup.
A wiring harness traceability program is a software that records and tracks the information of each individual wire in an automobile. The purpose of this system is to provide documentation for everything from manufacturing date, material composition, type number, location within the car’s electrical wiring systems, etc., allowing researchers to pinpoint any potential issues quickly without having to visually examine every inch of wiring throughout a vehicle.
As the cables are often visible, their design can be an important factor for aesthetic reasons or to optimize cooling. When it comes time to create your own cable assemblies and wire them up correctly, you’ll need these 5 things: 1) The wires of various types required by the circuit; 2) A schematic diagram showing how everything should connect together; 3) Electrical conductors (usually copper); 4 ) Insulation on electric power circuits;5). Solderless terminals If you’re looking for high-quality cable assemblies and wire harnesses, Cloom can get you what you need with advanced materials and techniques.

CHAPTER 1: What is SAE?



SAE, or Society of Automotive Engineers, is an international professional association that develops global standards for engineering industries.

The organization’s standards harmonize the production of different cables and electrical equipment types and offer a foundation for all manufacturers to be on the same page.

SAE standards enable manufacturers to improve the quality of products and meet safety guidelines.

The SAE cable in the scope of our article is used to establish a connection between a battery and other devices.

Specification of SAE Cable

The SAE cable can be called a ‘hermaphrodite’ connector because it features both male and female connectors.

The cables are generally used for automobiles and motorbikes though you can also use them for solar panels and alternative energy applications.

It is one of the components of a PCB soldered to provide extra sturdiness.

The SAE cable comes with two conductors and is commonly utilized to provide a maintenance charge to a car’s battery.

When harnessed with a battery system, the polarity of the terminals is designed to prevent any incidents of the short circuit even if the exposed ends come in contact with the metal vehicle chassis.

For this reason, the exposed terminals of the cable are connected to the negative outlet of the battery.

On the other hand, the positive end of a battery charger is often exposed and hooked up with the concealed SAE connector.

The circuitry of the battery charger also contributes to reducing any possible risks of short circuits.

Lead-acid batteries have higher chances of experiencing short circuits, so you must use a good quality SAE cable to mitigate the risks.

SAE Cable

Next, we will discover the implications of SAE connectors and discuss the widely used SAE battery connector.

SAE Cable

CHAPTER 2: SAE Connector

The SAE connector is mainly used for automotive applications and solar solutions.

But their versatility means you can also use them for other industries.

One of the common types of SAE connectors is the SAE battery connector.

Let’s find out a bit about it!  

SAE Battery Connector


Battery Connector

The SAE battery connector is a simple cable that connects your battery to other devices like chargers.

It has rings or clips at one end to connect to the battery and features a standard SAE connector on the other end.

The cable also has a 15 Amp to 25 Amp fuse to protect the battery.

You can set up the cable and connect a battery tender to charge your vehicle or motorcycle battery.

The SAE battery connectors don’t have the risk of a short circuit even if the unexposed end comes in contact with metal.

For this reason, they are safely suitable for use with different types of automotive parts.

For example, you can hook up a heated vest with an SAE cable with a round end and an SAE connector on the other end.

The SAE cable connects easily with the cable connector to establish a connection.

You can channel the SAE connector from the side of your bike and connect the battery tender or other devices.

The SAE battery connector features two ring terminals which you have to connect to the positive and negative points of the battery.

The terminals are generally color-coded in red and black for your convenience.

You can buy longer SAE connector cables that can measure 25 feet.

These are ideal for use in the garage, where you need power access for the battery charger, which can be located away from the vehicle.

Some manufacturers can use different connectors, but SAE is preferred because they are easy to use, affordable, easily available, and safe.

In the next chapter, we will discuss SAE plugs and then look at the adapter.


 SAE plugs can be used for basic wiring and general-purpose applications in motorcycles and cars.

The SAE plug at the end of the cable enables you to connect different accessories and charger boxes.

Most of the SAE plugs are compatible with motorcycle tank bags.

The SAE plugs are used across different industries and applications such as alternative energy, utility and off-grid solutions, recreational vehicles, vehicle installations, emergencies, and more.

Their versatility makes them suitable for navigation equipment, mobile phones, and laptops.

The SAE plugs are made for low-voltage though you can find many products which handle a higher amount of voltage for use in RVs, trucks, and other heavy-duty applications.

You can find different lengths of SAE plugs for automobiles of all sizes.

After the initial job of setting up the SAE, the plugs are over. You can look forward to a toolless assembly then onwards.

SAE Adapter

SAE Adapter

You will find different types of SAE adapters that can be used with various applications.

For example, you can have a USB adapter inside your vehicle (we will discuss SAE to USB later) or use a male-to-female adapter to establish a connection.

Another type of SAE adapter is commonly used to connect traditional SAE chargers or jumpstart equipment to newer cables.

These are sometimes used in power sports applications and automobiles and provide an easy way to connect different equipment.

Generally, the adapters are designed to achieve minimal power loss and maximum current flow.

One SAE adapter is common in cars and helps light up your smoke.

The convenient SAE to electrical lighter adapters sit comfortably in the dashboard of your vehicle and are connected to the battery on the other end.

Different accessories and equipment manufacturers also produce custom adapters to accommodate their products.

For example, you can find custom adapters that fit with chargers, solar panels, heated clothing, GPS, and other SAE devices.

Now it turns out to find out more about SAE to USB cable.

When choosing the right SAE cable, knowing what type of cable you need first is important.

SAE cables come in all shapes and sizes and are made to suit different needs.

We have already discussed applications like heated clothing and battery chargers that use SAE cables.

Technological advancement and lifestyle changes have led to new types of SAE cables to meet our modern needs.

We use gadgets as a part of our daily life that need a power source to keep functioning.

Many companies have started making SAE cables geared towards the gadgets like SAE to USB cables.

SAE to USB Cable


USB has become a popular format for different electronics around the world.

A common interface makes keeping all your devices up and running easy with simple charging options.

SAE to USB cables enable you to charge your cameras, mobiles, tablets, GPS navigation, and more by connecting them to the USB port.

SAE to USB cables has an SAE connector at one end and a USB port at the other.

The SAE connector is hooked to the battery unit of your vehicle or motorcycle, while USB connectors are placed on the dashboard or your fuel tank.

You can also find SAE to USB adapters, portable or dongle-shaped devices with a UBS port, and an SAE connector.

You may need a separate SAE extension cable to connect the adapter to the battery.

The SAE to USB connectors delivers different power levels, such as 1.1 Amp, 2.1 Amp, and 3 Amp.

 USB connectors

You should check the power compatibility of your device before connecting them to the UBS ports.

A low power level automatically protects the battery from total discharge.

Your battery’s voltage is another important consideration, as not all SAE to USB cables can sustain the same amount of voltage.

Some can sustain as high as 12 Volts, while others can support low outputs of 5 Volts.

You can find single or multiple USB ports on an SAE to USB cable or adapter.

The USB end sometimes has a protective cap to seal the ports when they are unused.

A few things also make your SAE to USB cable safe and efficient.

You can look for safety features like protection against overheating, short circuits, and high voltages.

Also, it’s better to go for cables and adapters, which are water, dust, and weather resistant.

In our next chapter, we will briefly overview the SEA connector extension cable.

CHAPTER 5: SAE Connector Extension Cable

Extension Cable

You may often not find the length of your SAE cable adequate for your purpose.

Sometimes the battery chargers must be connected to a wall AC outlet, and the SAE cable may not reach the vehicle parked outside.

You may also want to have some freedom and charge your devices sitting by the side of your motorcycle.

Sometimes the standard battery SAE harness falls short in length, leaving you in a fix!

An SAE connector extension cable comes to the rescue by offering you an extra cable length.

You can connect them to the SAE plug and hook the other end to your device’s battery charger.

SAE cables have specific standards which define their scope and application.

We will take a look at the common standards in the next chapter.

CHAPTER 6: SAE Cable Standard

SAE cables have different standards suitable for use in the automotive industry. J2183, J1127, and J2863 are some of the standards in use.

We will look at some common standards and determine what they are used for.

J2183 is a single-core SAE cable supplying DC electricity between 60 and 600 Volts.

You can use them for high-energy applications like solar grids and high-power automotive needs of trucks and RVs.

J20320 SAE cables are ideal if your job involves assembling ignition cables.

The J1127 is the commonly used low-voltage battery cable used in motorbikes and cars to connect the battery to different devices using an SAE plug.

The J1128 is the low-voltage primary cable necessary to charge and jumpstart your vehicle battery.

J2863 is meant explicitly for an automotive trailer tow connector and can withstand high loads of DC.

Usually, you don’t have to confuse yourself by remembering and evaluating all the SAE standards.

The manufacturers of SAE cables duly declare the specifications of their products and the applications so that you can choose easily based on your needs.

We have almost arrived at the end of our article.

Before wrapping things up, we will look at different types of SAE connectors to cables.

CHAPTER 7: SAE Connector to Cable


 As we have already discussed, you can use different SAE connectors for the cable.

You need to determine your need and application to choose the right connector.

We will explore the common type of connectors so that you can easily choose.  

SAE Connector with Leads

Connector with Leads

SAE connector with lead is used as automotive cables and is suitable for rearview camera systems.

The cables have a standard SAE plug at one end while the other is exposed to connect them to any wire or connector.

The SAE cables are designed to withstand high heat, oil, solvent, and abrasion levels.

The insulation material gives the cable a low-temperature resistance and high scrape strength.

SAE to SAE Connector

As the name implies, the SAE to SAE connector comes with SAE plugs at both ends.

You can use it for automotive wiring and connecting various vehicle and motorcycle accessories.

The cables are also suitable for military, industrial, and agricultural use and work with older SAE models without a problem.

The SAE cables are also made to be solvent, heat, and weather-resistant.

You can use them for any application that demands DC power transfer.

Generally, the cables are smaller over a mold, allowing you to fit them in tight spaces.

SAE Connector with Battery Clamp

with Battery Clamp

You can take the help of an SAE connector with a battery clamp to supply power to your devices from the battery directly.

It features a conventional SAE connector on one end and two clips or clamps on the other to connect to the battery.

The clamps are color-coded in red and black to know which goes to the positive and which connects to the negative.


SAE cables have many applications in the automotive, agriculture, military, and renewable energy industries.

After reading this post, they come in different specifications, which you must be aware of.

Knowing the specifications is necessary for choosing the right SAE cable and the success of your project.
