Transmission Wire Harness

Product Introduction

Our rust-proof transmission wire harness is made for extended, worry-free use. It fits nicely in cars, trucks, and many machines. We use strong plastics and coated metals to ensure the harness does not break or rust prematurely. This means fewer stops, fewer fixes, and steadier work. We also use 100% copper wire, which helps send clear signals and strong power. We cover and wrap each part of the harness to keep it safe. The shaped parts near the connectors help block water, dirt, and dust from entering. Shrink tubes and cloth wraps keep wires from rubbing or breaking. We test each harness under heat, shaking, and salt to ensure it remains strong in real-world use. We also add clear labels to help workers install and repair it straightforwardly.

Product Advantages

Custom Molded Multi-Branch Wiring Harness

A multi-branch harness is used when multiple wires need to reach various locations simultaneously. We shape this harness to fit your transmission’s layout. Each branch splits at just the right point, which helps the transmission wire harness stay neat and easy to place. Soft molding around the connectors adds extra strength and keeps out dust and water. This design helps stop loose joints and saves time during setup. Each branch sends power and signals to sensors and other key parts.

Protected Cable Assembly with Main Connector

This cable assembly features a single main connector that secures the entire harness. The main plug is housed in a hard case that helps keep out oil, dirt, heat, and other elements that can damage the wires. Small clips hold the harness tight inside the transmission. Behind the connector, the wires spread out and remain wrapped, preventing them from rubbing against each other or breaking. Even with shaking or prolonged use, the harness stays safe and steady.

Simple Pigtail Wiring
Harness

A pigtail harness is a quick and low-cost choice. It has one or a few wires with connectors on the ends. It might send power to a sensor or a small light. It is concise, straightforward, and easy to incorporate. We provide them with ready-made ends, allowing workers to add them quickly. Each pigtail has a safe outer cover, strong wire, and rust-free pins. Even though it is small, it stays secure and steady. This compact design ensures seamless integration and reliable performance within larger electrical systems.

Solution

Our team studies your wiring plan and makes a digital layout. After that, we create a sample. With innovative tools and clean methods, we make each joint strong and steady. We test for clean power flow and safe insulation to ensure the transmission wire harness functions properly.

Wire Harness with Mounting Bracket

Some harnesses need a built-in bracket. We add a metal or plastic bracket to the central part of the harness. It features small holes for screws, allowing you to attach it to the frame or housing. This keeps the harness firm, preventing it from sagging or shaking excessively. The bracket also helps reduce the strain on the wires, allowing them to last longer.

Complex Structured Wiring Harness

Some machines need very complex harnesses. These may have many wires, connectors, shields, or even fiber lines. Big trucks and heavy machines often require numerous sensors and connections. For these cases, we make layers or smaller harness groups. We route wires so they do not cross badly or wear down. We add wraps or braids for extra strength. Each connector is clearly shaped so that workers can plug it into the right spot every time.

Flat Flexible Circuit (FFC) Cable Assembly

FFC cables are fragile, light, and easy to bend. They have flat copper strips inside a soft plastic layer. They fit well in tight spaces and can bend many times without breaking. They also help cut weight and save space. They carry signals well, stay cool, and spread bending stress evenly. FFC cables are a smart fit for tight transmission areas where space is small and movement is high.

Material Recommendation

Tin‑Plated Copper

We use oxygen-free copper because it works well for both electricity and communication. The signal stays clean, and its cleanliness helps keep the heat down. The tin plating on copper keeps it from rusting and makes it easy to bend without breaking. These wires are great for places where there is a lot of heat, humidity, or movement. They help the dashboard wire harness last longer and be more durable.

Plastic Granules

Plastic granules are small pellets that are used to make jackets, clips, and shells for connectors. They use strong materials like ABS, nylon, and PVC. These materials won't catch fire, crack, or get too hot. They are helpful for making parts that don't change shape or break when stressed. Because of this, jackets and connections last longer and can handle bad weather better.

Heat‑Shrink Terminals

Heat-shrink terminals make sure that wire junctions don't get damaged by making a tight seal. The tube gets smaller as it gets hotter, which makes it fit tightly around the wire. It keeps dirt, water, and vibrations away. Some tubes have glue inside to make the seal even stronger. This makes it less likely that wires will come loose. We trust them to make sure that every connection is safe and will last.

PVC Tubing

Because PVC tubing is flexible, soft, and strong, it can cover wires. It can handle water, grease, cuts, and long-term wear and tear. It works no matter how hot or cold it gets. It keeps wires from rubbing against each other by putting them together. It also makes wires last longer by lowering the tension at bends.

Automotive Connectors

Our connectors are the best because they have strong locking clips and metal contacts. Many of them have covers that keep dust and water out. Because each connection has its own shape, you can't plug them in backwards. High-quality connections make the whole dashboard wiring harness stronger and last longer.

Industries and Applications

Automotive & Vehicles

We make and sell wire harnesses for a range of vehicles, such as cars, trucks, and off-road vehicles. They fit perfectly in hard-to-reach places like dashboards, engines, and gear parts.

Agriculture & Construction

Tractors, excavators, harvesters, and cranes have to deal with dirt, dust, humidity, and heat. Our transmission wire harnesses keep them working all year long.

Marine & Power Systems

Marine and power systems, like generators, ships, and boats, can be damaged by salt, storms, and moisture. Our harnesses prevent wire rust, regardless of terrain.

Industrial Machines

Robots and other industrial equipment need stable connections for their sensors and motors to work. Our harnesses keep this area clean and safe.

Aerospace & Defense

Aircraft and drones in the aerospace and defense industries need strong, light wiring. We put our harnesses through a lot of tests to make sure they are safe to use in flight.

Renewable Energy

Wind and solar power, for example, need clean power lines to work. Our wire is made to send information and electricity without making any noise.

Compact Harness Layouts for Tight Gear Spaces

We make harness arrangements that work in small, tight spaces. We carefully plan out each wire path, taking out any unnecessary turns and loops, to make sure that the routing is as good as it can be. We use thin, flat wires to keep things in order in small spaces. The way every connector, sensor, and cable is placed fits the shape of the gear compartment. This helps the heat safely escape and keeps the wires from hanging down. The transmission wiring harness is now safe, easy to use, and comfortable for long periods of time.

Multi-Layer Insulation to Stop EMI

To keep clean signals safe from electrical noise, you need a lot of covers and shields. When the power and signal cables are close to each other, we use foil, braided shields, or tight twists to keep noise from getting in. These layers help keep the signal clear, even when there are strong motors or thick power lines nearby. Because of this, the sensors and controllers can work well and steadily.

Precision Crimping and Termination

Using the right tools, each wire is crimped with the right amount of pressure. After this, every joint will be strong, clean, and safe. Sometimes we'll solder some parts together to make them easier to hold. We check how strong the draw is and how clean the touch is with each pin. This careful work makes sure that signals travel without interruptions, which is why every piece of equipment and system works well over time.

Careful Planning, Detailed Checks & Safe Shipping

A modern machine does the cutting, stripping, and crimping of each wire to size. After crimping, we check that the junction is strong and safe. When we see a tight turn, a sharp edge, or any other possible danger, we never ignore it. We talk to you and give you other options. People also really value open and friendly conversation. We want you to always know how our processes work, why they work that way, and how they affect your machine.

We don't make wire harnesses to fit your needs; we make them to fit your needs. Start by saying what you need in simple terms. Please tell us what the transmission wire harness does, where it will go, and how much space it will have. Next, our experts will take your ideas and requirements and turn them into a design that makes sense. Using CAD software, we will make a map of the entire transmission wiring harness.
