A clear wire harness drawing helps manufacturers quote faster and reduces the risk of sample rework. For B2B buyers, the drawing should connect engineering information with production, testing, packaging, and shipment requirements.
What to include in a wire harness drawing
- Connector model, terminal type, and mating part
- Pinout, circuit number, and wire color
- Wire gauge, wire type, branch length, and tolerance
- Sleeve, conduit, tape, heat shrink tube, and protection material
- Label position, barcode, and identification needs
- Continuity testing, visual inspection, and application-specific checks
Common RFQ mistakes
Many RFQs miss connector part numbers, branch length tolerance, label position, or testing requirements. These missing details can cause different suppliers to quote different structures and prices.
