Understanding specifications ensures the harness meets electrical and mechanical requirements.

• Examine wiring diagrams and BOM
• Identify wire gauges, colors, lengths, and connector types
• Note special instructions such as shielding or twisting

Organizing tools and components reduces assembly errors.

• Set up harness board according to layout
• Gather wires, terminals, and labels
• Verify calibration of crimping and stripping tools

Accurate wire lengths ensure proper fit and routing.

• Measure wire lengths per drawing
• Cut wires cleanly using approved cutters
• Strip insulation to specified length without damaging conductors

Proper identification prevents routing mistakes later.

• Apply heat‑shrink or adhesive labels
• Match label codes to engineering documentation
• Place labels away from termination points

Correct crimping ensures electrical continuity and mechanical strength.

• Select correct terminal type and crimp die
• Insert stripped wire and perform crimp
• Inspect crimp for pull strength and deformation

The board ensures accurate routing and bundling.

• Route wires according to layout pins
• Maintain bend radius requirements
• Group wires by function or connector destination

Bundling protects wires and maintains organization.

• Apply cable ties or lacing cord at intervals
• Add protective sleeving or heat‑shrink tubing
• Ensure no excessive compression on wires

Final termination completes the harness assembly.

• Insert crimped contacts into connector housings
• Verify locking tabs engage properly
• Add strain‑relief components if required

Testing confirms the harness meets functional requirements.

• Conduct continuity and insulation resistance tests
• Verify pin‑to‑pin mapping
• Document test results for traceability
