Product Advantages

Our tractor wire harness and trailer wiring harnesses offer numerous clear and valuable benefits that help farmers in their daily work and keep the machine safe for an extended period.

Strong Weather Protection

The tractor wire harness is designed for withstanding harsh outdoor use. It features sealed plugs and robust covers that prevent water, dirt, and dust from entering. Many plugs are IP67-rated, which means that no dust can enter, and the harness can even remain safe in water for a short time. The covers resist oil, grease, mud, and farm sprays. The harness can work in icy weather (–40°C) and very hot weather (+105°C) without breaking, melting, or cracking. Extra support at each plug stops the wires from pulling out when the tractor shakes on bumpy ground. Even after many years, the harness stays safe and firm where other wires would fail.

Correct Electrical Power

These harnesses are especially made to carry the high voltages for the vehicle system. Built-in fuses and relays add extra safety and control. Each fuse (13–40 A) stops overloads and protects the system. Relays allow small switches to control large tools or pumps without overheating or burning. The plugs, such as Deutsch DT or Molex, feature solid pins that form strong, safe, and low-loss connections. This ensures your tractor receives steady power for pumps, lights, fans, and motors at all times.

Custom Fit

Each tractor wire harness is designed to match the shape and size of your tractor or trailer. For the accurate fit and exact power supplying system, these harnesses are designed exactly to your needs. You can simply install or remove it for its smooth connecting features. Every wire is marked separately for ease of use. The plugs only fit into the right parts, so you cannot misconnect them. Installation becomes easier with this smart feature. You can design or select the harness according to your vehicle's needs. You can also ask for extra parts for your harnesses.

Long-Lasting Performance

Fils et câbles

We use only tinned copper wires from trusted brands. The wires are flexible and covered with PVC or XLPE. We select the thick copper cables for the harnesses. Thick harnesses can transfer more power and accurate signals. The wires can handle the high pressure and tough temperatures without breaking.

High-Quality Raw Materials

We use the most durable plastics that can resist the hard uses. Nylon6/66 is often used because it is tough and safe for engine use. Each plug is carefully molded for a perfect fit. Using the right plastic makes connectors strong, safe, and long-lasting.

Bellows

We protect wires inside corrugated tubes where needed. It covers the wires and protects the inner harness materials safe from harmful objects and tough weather. The black color protects against sun wear. In many cases, we also add braided covers for more safety. This helps the tractor wire harness last longer, even in rough or dirty areas.

Insulation Tape

At the final step, we wrap the wires with tape for added safety. We use either PVC or cloth tape that meets safety regulations. The tape stretches and sticks tight to seal the harness. It blocks water, heat, and shaking. We wrap in a spiral or overlap style to fully cover the wires. Good tape keeps wires from coming loose, stops sparks, and keeps the harness safe.

Braided Shielded Network Pipe

For wires that carry signals, we use braided sleeving. This is made from copper or steel braid. It blocks outside noise that can disturb signals. It also works as a ground to keep signals clear. A thin PVC cover is added for more safety. This is very important for ECU wires and sensor lines. It keeps signals clean and systems stable even in harsh conditions.

Nylon Cable Tie

We use nylon ties to hold wires neatly together. These ties are rigid, flexible, and safe under sunlight. They hold wires firmly but allow a slight movement to reduce damage from shaking. The edges are smooth, so they do not cut into wires. We choose the right size tie for each bundle to keep wires neat and safe. This makes the tractor wire harness stronger and more secure during heavy use.

Solution

Our engineers provide comprehensive wiring solutions for tractors, trucks, buses, and a wide range of other vehicles. First, we assess your wiring needs and review the system maps. Then we design a harness that covers everything.

Custom Tractor Wire Harness

In this harness, we plan for the parts you need, like alternator wires, starter wires, headlights, tail lights, sensors, switches, and extra tools. We only add the parts you want, nothing extra. For example, a tractor harness can include a 4-pin OBDII port or a 7-pin trailer plug if you ask. We build the harness on a layout board, ensuring every wire is placed in the correct spot. Each joint is crimped or soldered with care and thoroughly tested for safety. Fuses and relays are placed in sealed boxes to protect them from moisture and ensure their safety.

ECU Wire Harness Assembly

If your machine uses an ECU (Electronic Control Unit), we build special harnesses that connect every sensor and power line. Each ECU pin is wired carefully, and twisted or shielded wires are used to block noise if needed. To protect signals, we add foil shields, braided covers, or spiral wraps. The harness can also include sealed plugs that connect directly to the ECU and service ports, such as OBD connectors, for testing purposes. Before shipping, we test every ECU harness using tools that verify signals, resistance, and voltage. This ensures your ECU will function properly with no errors or weak signals.

Complete Vehicle Wiring Harness (Main Wire Loom)

The complete wiring harness, also known as the main loom, connects the entire system of your vehicle. We build it to fit the frame, cab, and body of your machine. The harness kit comes with all the essential parts for your vehicle. The loom features plugs for all components, from headlights to trailer sockets. Each wire is cut to the exact length required, with no extra slack and no stretching. This lowers stress on plugs and makes installation fast and straightforward.With these harnesses, complete vehicle wiring harness remain stable, clear, and strong
