Injector Connector Pigtail
2004.5 - 2016
LLY LBZ LMM , and LML
The wiring connector at the injector is a common source of issues on the LLY, LBZ, and LMM Duramax engines with injectors #2 and #7 being the most likely to cause problems and set injector circuit codes, possibly even triggering limp-in mode. Many injectors have been needlessly replaced over the years when the true source of the problem was a poor connection that could have easily been remedied with a new Duramax injector connector pigtail.
Please note that this listing is for a fuel injector connector pigtail ONLY. An injector is NOT included and is shown for illustration purposes only.
