Product Introduction

Wires in modern vehicles must be both smart and secure. The ECU connection and Y-split harness that make up our ECU DCU wire harness allow the vehicle's control system to provide power and data to all parts. Clean power with little noise and loss is the goal of every wire's design. It is shielded from bending or wearing out by thick covers. Both parts get electricity at the same time due to the Y-split design, which divides a single main wire into two smaller ones. Safety, speed, and strength tests are done on all of the parts. For maximum energy flow, the ECU harness wire gauge is used. No dust or water may get into the ECU wire harness since the junction is always snug and sealed. Every wire is neatly and tightly secured.

Product Advantages

Diagnostic/Interface Cable

Using our Diagnostic/Interface Cable, you may connect your vehicle to a scanner. Vehicle repairs are facilitated by the rapid and seamless flow of data. The twisted and attached wire inside helps to keep the signal clean and prevents noise. A single cable may be used with many types of cars because of its flexibility with different systems. It never loses its grip; the plug latches securely. The coat is thick and durable, so it will last a long time. We check each one to make sure it delivers data reliably and cleanly.

Automotive Connector Assembly

We make sure every connector is sturdy, secure, and ready to withstand any task. It has non-rusting metal pins and a heat-safe plastic structure. It is resistant to heat, vibration, and water. Wires cannot move or short out due to the firm grip. Each and every time, our ECU wire harness connection fits exactly and securely. Hand inspection ensures that every crimp is clean. Each item is carefully checked before shipment to ensure it meets our high security protocols.

Multi-Branch Harness

Wiring a home becomes a breeze with our multi-line harness. It facilitates the efficient transfer of data and electricity from a single large line to several smaller ones. Without tangling, it connects with sensors, lights, and other components. You can easily identify the correct line thanks to the labeling and vivid colors, like the GM wiring harness color code. Doing so allows for more room and maintains a clean vehicle. This organization ultimately enhances your home's value and functionality.

Solution

We make complete wiring kits that make setup fast, safe, and easy. Each kit comes with multi-color plugs, custom wires, and coiled lines that fit together perfectly. Every part is thoroughly tested to ensure it functions properly. The kits help save time, cut mistakes, and make the car safer.

Multi-Color Connector Set

Color helps make wiring quick and easy. Our plugs come in bright, transparent colors that match the tags, so you never mix them up. We follow car color systems, such as GM coding, to maintain clarity. Each plug features small seals and locks to prevent dirt and water from entering. The plastic remains strong in high heat and under heavy workloads. Each plug has labels to help techs find the right fit fast.

Coiled Main Harness

Our coiled main harness bends and moves with ease. It stretches and returns to its original shape without breaking. It's perfect for parts that move frequently, such as doors, steering, or folding arms. When still, it stays curled tight. When pulled, it stretches smoothly. Inside, the ECU DCU wire harness wire gauge wires transmit power steadily and safely. Extra layers protect it from cuts, shocks, and heat. The spiral shape keeps it from tangling or wearing out.

Industries and Applications

Multi-Strand Fine Copper Wire Stranded Wire

We twist the copper that makes up our cables into many thin strands. Because of this, they are flexible, easy to bend, and great for small spaces. Each strand is protected from rust by a tin coating. Due to its excellent conductivity, copper is a great metal for use in power and signal transmission. The wires stay cool even when they are carrying heavy things. You can't break them by shaking or bending them.

Aluminum Foil + Copper Wire Braided Shielding

Twisted wires help improve signal shielding, but some suppliers don't handle the twisting pitch correctly. For example, some customers request 2 turns per inch of twisting, but the supplier only gives 1.5 turns. This is often because they don't have enough wire length, cutting corners to save material. We never compromise on materials or custom specifications.

High-Quality Plastic Granules

The starting material is clear, small plastic beads called resin. After they melt, they make parts that are strong, smooth, and shiny. We only use high-quality polymers like PA66, ABS, and PBT that can withstand heat and sunlight. We test each batch to see how well it can bend, chill, and stretch. The finished pieces fit together so tightly that nothing can get in, not even air or water. Because of this, they are ready to work hard.

DCU Automotive Connector

DCU connections are a design success because they are strong and last a long time. The body of each link is made of thick, strong plastic that doesn't melt or break. There are metal pins inside that are plated with copper. They are covered in tin or gold to keep them from rusting and to keep them working. These tiny seals make it water-, oil-, and dirt-tight. Fire-safe parts are put in place to slow the spread of fire.

ECU Automotive Connector

This part is vital to ensure the reliability and the smart performances. These connectors connect the wires to the machines. These connectors are made carefully to resist the bad weather and produce the exact data and power to the control system.  High-temperature thermoplastics such as PBT or PA66 are used to make the structure of these connectors. These are the most essential parts to connect each part to the other part.

Retardant Corrugated Tubing

Strong, flexible tubes protect wires from dust, water, and oil. The tubes can be bent without breaking. Not only that, but they also keep the sun from breaking or weakening them when they are outside. Because the plastic stops fires from spreading, cars and machines are safe from them. Every tube goes through tests for pulling, heat, and burn resistance. The shape stays the same, and the wires are safe from damage even after being outside for years.

Industries and Applications

Automotive & Electric Vehicles

Our safety belts make sure that buses, cars, and trucks can drive safely. They connect all the systems that control power and signals. The electric vehicle's power transfer from battery to motor doesn't lose any power at all. We make sure that the harness fits properly and has enough space by making it for each vehicle.

Industrial & Robotics

We made our safety harnesses so that machines and robots that work in factories every day can use them. Even though they have been bent thousands of times, they are still strong. The thick coating and shielding keep all signals fast and accurate, even when it's very hot and moving.

Commercial Machinery & Marine

The marine and commercial machinery industries work with ships, cranes, and other big machines that get a lot of use, dirt, and salt. Our harnesses will still be completely waterproof and strong even after a long day of use outside. They are resistant to heat and corrosion, which ensures that systems work safely.

Consumer Electronics & Medical

We make and sell small harnesses for use in home and healthcare electronics. Screens and tools get their messages loud and clear. We put a lot of effort into making and testing each one to make sure it will last for a long time and be safe.

Energy & Telecommunications

Our harnesses are used by both the telecommunications and energy industries to send data and power from solar panels. Even when it's hot, rainy, or heavily used, they keep their signals steady. The layers keep everything safe no matter what the weather is like, and the easy-to-follow instructions make setup a snap.

Precision in Every Connection

We put a lot of thought and effort into every part of our ECU DCU wire harness, even the plugs and pins. To make sure that every piece is the right length and width, we use special computer tools to plan out each structure. To make sure everything fits snugly and smoothly, each part is checked many times. The wires are easier to follow because they have clear laser markings on them. That's why we promise that our systems will always fit perfectly. Perfect fits make machines and vehicles work better, safer, and for longer periods of time.

Compact Design & Massive Performance

Our harnesses are strong, even though they are small. The wires are neatly arranged to cut down on bulk and weight. The copper inside makes it possible to send power quickly with less heat loss. The wires are safe from heat and danger because they are wrapped in a thin film. Snug crimps and strong plugs help keep energy from being wasted. These harnesses will fit snugly if your car or machine is on the smaller side. Even though they are small, they work hard, control their strength, and stay strong for many years.
