Ethernet Wiring Repair

WARNING: This page is about a different car, the 2019 GMC Savana 3500, 2019 GMC Savana 2500, 2019 Chevrolet Express 3500, and 2019 Chevrolet Express 2500. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • Do not splice wires or perform your own crimps.
  • Service harness kits will be released per vehicle and the kit will contain a length for each leg/peripheral device.
  • The lengths are designed to allow for some extra slack but loop-backs and hard turns or pinches are not desirable.
  • Twisted pairs are supplied with terminals already crimped.
  • If for any reason an Ethernet wiring repair kit is not available, the preferred repair procedure is to replace the entire harness.
  1. Remove the respective Ethernet connector from each module (end-to-end connection).
  2. Depopulate the terminals using the proper terminal removal tool from both connectors.
  3. Overlay the proper twisted pair provided in Ethernet Wiring Repair kit.
  4. Insert terminals into connectors.
  5. Reinstall connectors.
  6. Neatly secure Ethernet wiring to existing harness taking up extra length without pinching wires.
