What Information Is Needed for a Replacement Wire Harness?

The information required for a replacement wire harness depends on the existing assembly and available documentation. Providing the following information can help establish the required configuration and production requirements:
  • Existing wire harness assembly or sample
  • Part number or assembly identification
  • Available drawings or specifications
  • Wire, connector, and terminal information
  • Photographs of the existing assembly
  • Equipment or application information
  • Required quantity
  • Testing or inspection requirements
  • Known configuration changes or modifications
When original documentation is limited, an existing harness assembly and available product information can help establish the requirements for replacement production.
