Specifications
Key specifications to define before quotation
Final requirements should come from customer drawings, specifications, test methods, acceptance criteria, and project documentation.
| Harness drawing | Required for routing, branch lengths, termination, labels, and inspection requirements |
|---|---|
| Connector system | Customer part numbers or approved equivalent review |
| Wire identification | Labels, colors, markers, or documentation defined by project |
| Routing protection | Sleeving, heat shrink, tape wrap, tie points, and bend control reviewed per application |
| Testing | Continuity, polarity, and functional checks reviewed per harness design |

FAQ
Common RFQ questions
What documents help quote a wire harness assembly?
A harness drawing, bill of materials, connector and terminal part numbers, wire specifications, routing details, labels, testing requirements, and quantity are the most useful inputs.
Can harnesses include labels and routing protection?
Labels, markers, sleeving, heat shrink, ties, tape wrapping, and routing protection can be reviewed as part of the harness drawing and RFQ package.
