Custom Wiring Harness Manufacturing
Built for Manufacturers. Trusted for Decades.
Kwik Wire isn't just a retailer of classic car wiring harnesses — we're a manufacturer. For decades, we've built custom and OEM wiring harnesses in bulk for other companies who need a reliable production partner, not just a one-off vendor.
If you need a consistent supply of wiring harnesses for your product line, we can build them to your exact specifications, at the volume you need, on a schedule you can count on.
Who We Build For
We've built wiring harnesses for well-known names across a range of industries, including:
- Leach — heavy-duty harnesses for garbage truck production
- Monroe Truck Equipment
- Ingersoll Lawn Equipment
- JW Speaker
- Generac — harnesses for power generation equipment
- Agri-Fab — lawn and turf equipment
- Mercury Marine
Our ideal manufacturing partner is a company with an ongoing, repeatable need — not a single small batch, but a product that requires the same harness built again and again. That's where we can build real efficiency and consistency into your supply chain.
How It Works
1. Send us your specs. Provide a blueprint or wiring diagram for the harness you need. Every harness is different, so we quote based on your specific design.
2. We quote your volume. Tell us how many pieces you need — whether it's a small batch or ongoing production runs — and we'll provide a quote based on your requirements.
3. We build to your schedule. Typical turnaround is 3–4 weeks, though this can vary based on complexity and volume.
4. We ship nationwide — and into Canada. We manufacture and ship harnesses to customers across the United States and Canada.
