How should you verify the proper routing of wiring after inspection?

• A. Compare actual wiring with the schematic and labeling; verify harness routing per specs.
• B. Rely on memory of the technician about routing.
• C. Only check color codes at the ends.
• D. Assume routing is correct if no faults are found.

Answer: (A)

The important idea here is making sure the wiring harness is installed exactly as designed. To verify proper routing, you should compare the actual wiring with the schematic and with any labeling on the harness, and confirm that the harness path follows the routing specified in the documentation. This means tracing the harness from its origin to each termination, checking that every run, bend, clamp, and tie aligns with the diagram and that labels match the corresponding schematic segments. This approach ensures the path is correct, avoids chafing or interference with moving parts or heat sources, and confirms the installation meets the approved design.

Relying on memory isn’t reliable because routes can be forgotten or misconstrued. Checking color codes only at the ends doesn’t verify the overall path of the harness. And assuming routing is correct simply because no faults are found can hide misrouting that could cause issues later. Verifying against the schematic and per documented routing eliminates these risks.
