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.
- Remove the respective Ethernet connector from each module (end-to-end connection).
- Depopulate the terminals using the proper terminal removal tool from both connectors.
- Overlay the proper twisted pair provided in Ethernet Wiring Repair kit.
- Insert terminals into connectors.
- Reinstall connectors.
