Why Choose Custom Truck Wiring Harness?
When doing truck electrical system upgrades or developing new models, have you often encountered this problem: more and more light clusters, electronic control units, sensors, while the original wiring harness is getting more and more messy, and the wiring diagram is always halfway through the change and then fail? In fact, what you need may not be “keep tinkering”, but a set of custom truck wiring harness tailored for your truck project.
We are Linkwings, an engineered wiring harness manufacturer specializing in custom wiring harness development, with a long history of serving a wide range of medium and heavy duty truck, specialty vehicle and RV customers. From power distribution to CAN communication, from headlight clusters to rear trailer interfaces, we understand that truck wiring harnesses not only need to be energized, but also need to stand up to high temperatures, vibrations, and long-term operation. If you’re looking for a custom truck wiring harness supplier for your project that truly understands construction, delivery, and also communication, feel free to read on to learn more about our solutions.
What is a Custom Truck Wiring Harness?
Custom Truck Wiring Harness, is a wiring harness system that is tailored to the specific truck platform, functional configuration, electrical interface and mounting structure. It is different from factory standard parts or universal wiring kits, but is customized and developed for each vehicle’s actual application environment, equipment layout and functional requirements.
Including but not limited to:
- Main power harness
- Lighting system wiring harness (LED, warning lights, etc.)
- Communication wires (CAN bus, GPS, camera signals)
- Electronic control unit ECU connecting wires
- Rear body/trailer connection harness
Custom Truck Wiring Harness Process
Whether you’re developing a new platform, upgrading an older model, or customizing a special purpose vehicle for a client, Linkwings can provide you with a custom truck wiring harness solution that is solid from design, to validation, to delivery.
As an experienced custom wiring harness manufacturer, we understand that every truck is different in terms of construction, usage, and electrical needs. That’s why our customization process isn’t just a “build-to-order” process, it’s a systematic collaboration from an engineering perspective. Below is our complete custom truck wiring harness development process:
Step 1
Requirements Communication
You can provide drawings, electrical schematics, complete vehicle wiring plans, or just an actual vehicle and a few target features. We will discuss the following with you:
- Number and location of interfaces (ECU, power supply, light clusters, instruments, sensors, etc.)
- Operating environment (temperature, water, corrosion, oil, and abrasion resistance requirements)
- Functional priority and alignment
- Whether it involves rear body/trailer, on-board communication system, etc.
Step 2
Engineering Design
We will have a team of engineers to carry out wire harness branch design, plug layout, wire diameter matching, pin definition and protection level planning. And provide the following:
- Preliminary harness drawings or structural sketches
- Recommended material list (wire/jacket/terminal/connector)
- Interface definition table (with pin definition, current carrying capacity, insurance recommendations)
Step 3
Sample Making and Testing
Equipped with professional wire harness processing equipment and experienced production technicians, our sample production usually includes:
- Precision wire cutting, stripping, crimping
- Plug installation, waterproof encapsulation
- Coding and marking, terminal protection
- Conductivity test, short circuit test, insulation test
⏱ Typical sample production cycle: 5~10 working days.
Step 4
Customer Confirmation and Adjustment
After getting the samples, you can test the assembly, wiring layout and functional operation on a real car. If there are structural or functional adjustments required, we will respond quickly and revise the drawings to ensure that the final product is a 100% fit for your system requirements.
This stage is very critical, we will provide installation proposal drawings, wiring harness unfolding drawings or audio-visual support to assist debugging.
Step 5
Small Batch / Bulk Delivery
After the confirmation of sample parts, we can enter the formal mass production stage. We support small quantity order (5 sets, 10 sets) and can deliver in batches according to the production schedule. All products will be 100% electrically tested before leaving the factory and can be provided:
- Test report
- Installation drawings and wiring instructions
- Connector identification lists and serviceable manuals
Step 6
Follow-up Support
- Wire harness design files are stored for a long time, which is convenient for subsequent reorder or version update.
- Project follow-up engineers continue to support after-sales optimization, functionality expansion
- In response to the use of feedback, we provide alternative materials, process improvement proposals

FAQs about Custom Truck Wiring Harness
Q1: Can I make a custom truck wiring harness even if I don't have a complete drawing and only have the actual wiring needs on the car?
Can. We are very familiar with incomplete information at the beginning of a project. You only need to provide preliminary information such as photos of the actual vehicle, hand-drawn wiring sketches, connector models, and functional descriptions. Our engineering team will assist you in sorting out interface definitions, wiring structure, and make professional suggestions to complete the wiring harness design step by step.
Q2: What types of wire harness testing do you offer? Do you have test reports?
All factory wiring harnesses are 100% conductivity tested. We can also carry out insulation voltage test, short circuit test, tension test, waterproof performance verification, etc. according to customer requirements. Test report, wiring definition table and installation schematic can be attached to facilitate commissioning and after-sales maintenance.
Q3: Are the connectors and wires used in the harness brand selectable?
Customized options are available. We support customer-specified brands, such as TE, Deutsch, AMP, Molex, etc. We can also recommend Chinese industrial-grade alternatives according to the project budget. Cables are available in PVC, XLPE, Silicone, Teflon, double jacket, highly flexible oil resistant materials, etc. to meet different temperature resistance, protection, shielding and other needs.
Q4: Can you keep my project information and drawings? Can I repeat the order in the future?
Can. We create a proprietary data file for each project, containing drawings, interface definitions, production lots, sample records, and other information. Whether it’s a return order after one year or you want a version upgrade from an old harness, we can respond quickly without having to redo the design.
