I Need a Wire Harness Assembly

Sometimes the last thing considered in a complex system is the wiring harness. However, as with many sub-assemblies that make up a system, wiring harnesses have many variables that may affect the quote and the quoting process if these variables are not clearly defined early in the quote process. Following is the information typically required to complete an accurate and timely quote.

Basic Information Required for a Wire Harness Assembly:

  • Company Name
  • Address
  • Contact Name
  • Contact Information
    (Title, Telephone, Fax, Email)
  • Part Number
  • Rev Level
  • Date Quote is Required
  • RoHS/REACH Compliance Required
  • NAFTA Required
  • Print (if available)
  • Bill of Material (if available)
  • Quantity to Quote
  • Release Quantities


If there is no print or no BOM available, the customer will need to provide alternative information, as noted below.

For a simple prepped wire:
  • Wire AWG
  • UL Style
  • Wire Color(s)
  • Length of Finished Wire
  • Overall Length Tolerance
  • Blunt Cut
  • Strip and Retain (Strip Length and Tolerance)
  • Strip and Tin (Strip Length and Solder Type)
  • Packaging Requirement (bundled, bagged, boxed, etc.)


Also, don’t forget there are two ends to the wire. Do you want both ends prepped the same?
