GM Duramax LLY Injector Harness Upgrade Kit For 2004.5-2005 LLY Duramax Engines

The LLY Duramax engines have a known issue with the injector harness wires for #2 & #7 injector where you will throw a CEL, code and go into limp mode. There is a temp fix callled the Ice Pick fix which can get you running again if you have the ablility to clear the code. This is only a temperary fix and it will happen again. This kit will fix it permanently so you do not have to worry about being left stranded on the side of the road somewhere with no way to clear the code and get out of limp mode. You will need a tool for crimping wire connectors and a socket set for the harness bracket.


Kit Includes:

  • 2 Injector wire leads (#7 & #2) with injector plug end
  • 6 Crimp wire couplers
  • 2 harness brackets
  • 2 bracket bolts
