Frequently asked questions
What is Harness Atlas?
Harness Atlas is a free global directory of wire harness and cable assembly manufacturers. Every listing is plant-level — the capabilities, certifications and served industries of individual production sites — so procurement teams can match an RFQ to the exact facility that can build it.
Who is Harness Atlas for?
It is built for procurement, sourcing and supply-chain teams, and for design and manufacturing engineers who need to find, qualify and compare wire harness and cable assembly suppliers worldwide.
Is Harness Atlas free to use?
Yes. Browsing plants, comparing suppliers side-by-side and sending RFQs is free for buyers. Manufacturers can claim or create a listing for free.
What is the difference between a wire harness and a cable assembly?
A cable assembly groups a small number of cables, often terminated with connectors and overmolding. A wire harness binds many wires and circuits into a single loom for a complete system. Most manufacturers in the directory build both.
How do I find a wire harness manufacturer for a specific country or industry?
Browse by country, industry, capability or certification from the homepage, or open the directory to filter every plant. Shortlist suppliers and send one RFQ to multiple manufacturers at once.
