Tired of high prices, low quality, and shipping delays? We deliver OEM-grade harnesses with 28 years of manufacturing backbone — engineered for RV, camper, and fleet applications.
✅ ISO 9001 ⚡ IPC-A-610 🌍 48h samples

🔧 28-year factory · 60,000 sq ft · Shenzhen
The RV and fleet industry runs on reliable electrical architecture. Yet, most importers face the same costly headaches:
Middlemen add 30–52% to OEM harness costs. You pay for layers that don't add value.
Standard wire harness lead times now exceed 14 weeks; critical for seasonal camper launches.
Low-grade insulation, improper crimping, and no end-of-line testing cause camper electrical fires.
Volatile shipping costs from distant suppliers erode your margin before the product lands.
🔍 Industry Insight: According to the 2026 Electronics Supply Chain Outlook, early supply chain engagement in NPI helps identify constrained technologies before production ramps. Yet 68% of RV OEMs still source harnesses from fragmented suppliers with no engineering support. You deserve better.
HUB Circuits combines 28 years of PCB manufacturing, 25+ years of PCBA, and 20 years of custom cable design to deliver true end-to-end wiring harness solutions. No middlemen — just engineering.
PCB fabrication, assembly, cable harness, box build — all under one roof. Cut logistics cost by 37% and eliminate multi-supplier coordination.
Every fleet flex wiring harness undergoes automated continuity, Hi-Pot, and pull-force tests. < 0.3% field failure rate — 50x better than industry average.
Send us a sample or drawing — we handle redesign, requalification, and obsolescence support (critical for long-run camper models).
Our Shenzhen hub ships to USA in 8–12 days express (DDP/FOB). Air freight for urgent Lance truck camper wiring harness orders — 5 days.
RoHS, REACH, UL, ISO 9001:2025, IPC-A-610 Class 2/3. Halogen-free, flame-retardant materials as standard — no extra cost.
Our engineers review every order — cloud-based CAD/PLM collaboration reduces NPI timeline by 40% (Industry Analysis, 2026).

“We switched our Lance truck camper wiring harness supply to HUB Circuits. Cost dropped 28%, lead time from 16 weeks to 9 weeks. Their engineering team even improved the connector sealing — no more warranty claims.”

“Their fleet flex wiring harness handles extreme vibration — we tested 1M cycles. Zero failures. Plus the DDP shipping saved us $1,200 per container. Stick with them.”

“HUB Circuits is not just a supplier — they’re an engineering partner. The box build assembly (harness + enclosure + PCB) reduced our vendor list by 4. NPI cycle cut 40%.”

We offer no MOQ for samples (1–5 pcs). For production, typical MOQ is 100–300 pcs per variant, but we can flex based on your forecast. Contact us for custom quotes.
Absolutely. We provide reverse engineering and redesign services. Send us a sample or 3D scan, and we’ll deliver a production-ready harness with full compliance documentation.
We offer DDP (Delivered Duty Paid) — no surprise fees. Air express 8–12 days, sea freight 25–30 days. We also warehouse in Los Angeles for just-in-time delivery.
All harnesses are ISO 9001:2025, IPC/WHMA-A-620 Class 2/3, RoHS, REACH, and UL recognized. We also provide FCC, CE, and TUV upon request. Our factory is certified for halogen-free manufacturing.
48h rapid quote, then 5–7 days for sample harnesses. For complex Lance camper harnesses with custom connectors, add 2–3 days. We use automated wire processing to accelerate turnaround.
Our total cost (product + shipping + duty) is typically 25–45% lower than US domestic suppliers, while meeting or exceeding quality standards. Combined with DDP terms, you get a predictable landed cost.

A truck wire harness is like the nervous system of a truck. It is a group of wires, connectors, and terminals that link all the electrical parts together.
Printed circuit boards are at the heart of countless electronic products, from consumer devices to industrial control systems. As modern electronics become smaller and more sophisticated, PCB layouts are becoming increasingly compact, with more components, interconnections, and functional circuits integrated into limited board space.
Modern electronic products continue to become smaller, faster, and more functionally integrated. To accommodate increasingly complex circuits, manufacturers place more components and conductive paths within limited PCB space.
A Printed Circuit Board (PCB) brings multiple electronic components together through carefully designed circuits and conductive traces. When the board is operating normally, each component performs its intended function and works together with the rest of the circuit. However, the failure of a single resistor, capacitor, diode, IC, connector, or other component can affect the performance of the entire system.
