The Problem
You're Stuck Between Three Bad Options
- China Manufacturing
500 piece minimums, 8-12 week lead times, and wire harness quality that's a complete mystery until it arrives.
- Aerospace Suppliers
Perfect documentation, perfect processes, and perfectly shocking prices. $5,000 for 10 simple wire harnesses.
- Local Shop
"Maybe next month? Let me get back to you..." - if they even return your call.
The Solution
Enter MiniProto: The Sweet Spot
Fair Pricing
Not the cheapest (China) or most expensive (aerospace). We're the "just right" option for quality and value. No hidden fees, no surprise upcharges, no minimum order padding. Just honest pricing for professional wire harnesses that won't break your budget or your schedule.
2 weeks Delivery
Fast enough to keep your project moving, without the panic pricing. Stock connectors might be even faster. While others are stuck in 8-week lead time limbo or charging rush fees that cost more than your wire harness, we're already building your assembly in our Kingston, NY facility.
True No-MOQ
Order 1 wire harness or 500. Perfect for hardware startups testing prototypes, small manufacturers, or fixing yesterday's mistake. No artificial minimums, no "piece price breaks at 100 units," no pressure to order more than you need. We built this nimble operation for engineers who just need the damn wire harness to work.

Our 6-Step Wire Harness Manufacturing Process
Design Review & Engineering Analysis
Our wire harness engineers review your specifications, check for potential issues, and optimize the design for manufacturability. We verify connector compatibility, wire gauge requirements, and overall harness routing.
Still deciding how the run should be grouped or protected? Start with our wire harness bundling guide.
Material Sourcing & Inventory Check
We verify availability of all connectors, wire types, and wire harness components. Stock items ship immediately; custom connectors are sourced from our approved supplier network including DigiKey, Mouser, and direct manufacturers.
Wire Preparation & Cutting
Precision wire cutting to specified lengths with automated stripping equipment. All wire ends are inspected for proper strip length, conductor condition, and insulation integrity before wire harness assembly.
Crimping & Connector Assembly
Crimping follows IPC/WHMA-A-620 workmanship practices using calibrated tooling. Each crimp is visually inspected and pull-tested to ensure mechanical and electrical integrity of the wire harness connection.
Assembly & Wire Management
Complete wire harness assembly with proper routing, bundling, and securing. Custom labeling, heat-shrink application, and protective sleeving as specified. All wire harnesses follow documented work instructions.
Testing & Quality Verification
Electrical testing including 100% continuity and isolation verification. Final visual inspection and packaging for secure shipment of wire harnesses.

Wire Harness FAQ
Common Questions About Custom Wire Harness Manufacturing
Answers to frequently asked questions about our wire harness services, wire harness manufacturing capabilities, and custom connector solutions for wire harnesses.
What is your actual wire harness lead time?
Our standard lead time for custom wire harness assembly is 10 business days from order confirmation. Wire harnesses using stock connectors and common wire types often ship faster. Complex multi-branch wire harnesses or custom connector sourcing may require additional time. We provide accurate lead times upfront during the quoting process.
Do you really have no minimum order quantity for wire harnesses?
Yes, we offer true no-MOQ wire harness services. You can order a single prototype wire harness or multiple units. While we're most efficient with orders in the $1,000-5,000 range, we welcome wire harness projects of all sizes. This makes us ideal for prototype development, small-scale production, and custom one-off wire harnesses.
Can you source specialty connectors for custom wire harnesses?
Absolutely. We can source virtually any connector for your wire harness project. Simply provide the DigiKey, Mouser, or manufacturer part number. Our supply chain includes major distributors and direct manufacturer relationships for both common and specialty connectors including circular, rectangular, automotive, and industrial connector types for wire harnesses.
What quality standards do you follow for wire harness manufacturing?
Our wire harness processes follow IPC/WHMA-A-620 workmanship practices for wire harness manufacturing. This includes proper crimping techniques, wire preparation, and assembly documentation. We perform 100% continuity and isolation testing on all wire harnesses before shipment.
What wire gauges and types can you use in wire harnesses?
We work with wire gauges from 18 AWG to 28 AWG in various insulation types including UL1007 (standard PVC), UL1061 (thin-wall), GXL (automotive), and silicone rubber wire for wire harnesses. We can also source specialty wires like PTFE/Teflon, shielded cable, and twisted pair configurations for specific wire harness applications.
What is your warranty on custom wire harnesses?
We provide a 60-day warranty against manufacturing defects on all wire harnesses. This covers workmanship issues including crimp quality, wire preparation, and assembly integrity. If we made an error in your wire harness, we'll remake it at no charge.
Can you handle complex multi-branch wire harnesses?
Yes, we specialize in complex wire harness assemblies including multi-branch configurations, mixed wire gauges, and assemblies with multiple connector types. Our engineering team reviews wire harness routing and provides manufacturing recommendations to ensure reliability and cost-effectiveness.
Do you provide custom labeling for wire harnesses?
Yes, we offer custom wire labeling services including heat-shrink markers, cable tags, and permanent identification labels. This is essential for complex wire harnesses where individual wires need identification for assembly or maintenance. Custom labeling can include part numbers, wire functions, or customer-specific marking requirements.
